Hi there,
It's best to do some research on your competitors before formulating a price for your services. It is highly dependent on your area. A $1000 for a wedding job elsewhere may be too much or too little in your area, so its best to find out what the average wedding photographer in your area charges.
Just some tips. Seeing as this is your first wedding job, the price you quote/set should be more flexible. In other words, you shouldn't be out to get as much money as you possibly can. Now as "odd" as this may sound, a lot of new wedding photographers come out wanting to charge what the veteran / seasoned wedding photographer charges. This is a big no no. For obvious reason. There are going to be many hiccups on your first job and in order to protect yourself you should consider that #1 you have no experience in weddings. It doesn't matter how mad your skillz are in photography, you will make mistakes. Lets face it... Weddings are stressful and there's a lot of stress involved. The first wedding gig will either make you or break you. This is why when charging clients, you should explain to them that this is your first gig so they know beforehand what to expect and what not to expect. Second, you should charge a little under what the average market rate is. The reason being... If you do a good job and didn't charge a whole lot, clients will be raving about your services - that word of mouth advertising is going to give a big boost for your business. And if you didn't do so well... you did ok... Clients won't be too too disappointed in what you gave them for final results. However, here's the main reason... If you did a crap job and you charged less than what everyone does, then they won't really be "out to get you". Now if you charged them the market rate and gave them crap... You might as well not show your face in the wedding scene for a long long time because they're going to go to their friends, family, co-workers and tell them all what crappy experience they had with you. I've seen this happen to 2 people in my city, and believe me... stuff like that sticks to your reputation for a long time if not forever. Just remember, if you are serious about doing more weddings in the future, there will be many many opportunities for you to make the big bucks, so don't rush into it and try to milk your clients just yet.
As far as prints go, most new wedding photographers just charge that seperately. Good practice when starting out would be just to charge what the lab charges... Give them the receipt and show them, this is how much it costed or costs. This shows that you are not trying to take advantage of them... This means good rep for you. You can always charge a percentage or a flat rate for arranging/organizing prints for your clients... like 10% or something like that is reasonable. But prints aren't where you're bread and butter are... unless you do prints from home or something (but its not very cost effective and the quality of home prints aren't near as good as lab prints unless you have a commercial printer at home). Majority of clients are fine with just receiving digital copies on DVD too, just as long as you state beforehand what you do and don't do.
As for gear... You're going to want a 2nd body. One body should have a standard zoom like a 17-55 2.8 and your 2nd body should have a zoom or fast prime (70-200, 50mm, 85mm). And you will want lots of extra batteries for your flash. If you know the schedule of the day and will have "break/flex time" bring a laptop so you can upload and backup your photos during that time. Backing up photos is very important, memory cards arent perfect and they can get corrupted at the most unexpected times.
Lighting in churches are harsh... Depending on the design of the church you could have a mix of diffused light from frosted glass, orange light, candle light... lotsa shade... it's going to be difficult getting proper WB in there, so best bet is to go to the church before the wedding day and get a handle of the setting you're going to be working with (you will have little or no time to fidget with your camera settings / experiment on the wedding day), its going to be bang bang bang done. So be prepared for that.
Also be sure to let your client know to advise guests that you are the photographer for the day and that people need to give you space. If brother bob and uncle joe are running around taking pics and getting in your way, you will not be responsible for not being able to get the shots you need. Guests are mostly respectful of you and will not get in your way... Its the ones that are "photo junkies" that you need to be worried about. They tend to "assume" the role of main photographer... because they are the clients relatives or whatever... lol... it happens... And you can say, "excuse me, i need to get some shots, you can get some after me", but that's about it... You can't do much after that if they still don't give u the space (getting into arguments or yelling at them is not going to look very good for you... give them 1 warning and then afterwards, just let it be - you can justify to the newly weds afterwards why some shots weren't possible, etc... they can't complain).
Anyway, i wish you all the best on your first wedding. Be sure to drink lots of water and bring little snacks like granola bars or power bars to eat while on the go.
