It is very hard to decide on pricing schemes. I have the same feelings as some others: your prices are much too low. For us Americans, he's charging roughly $150USD for the "Class A" package.
Always, always, always charge an hourly rate. Clients can be very abusive and may take advantage of you if they find you in the least bit vulnerable. My recommendation for how to charge is as follows:
First, volunteer for some open-source projects at
Source Forge's Help Wanted System. Open source projects almost always have no money involved but can generate a
LOT of exposure. Make sure to get the project to credit you on their site.
From this experience you should get a few things: the first being an understanding of working with a client and a great knowledge of how you work. You should keep track of how long it takes (actual work time) for you to get projects done. Keep track of
what takes
how long (EX: 4 icons took 2 hours, basic HTML layout took 6 hours, etc).
Lastly, from volunteering for open source and showing how awesome your work is, since you remembered to get yourself credit on their site and/or in their project, clients will come to you.
At this point, you have the client send you a message asking for a quote on their project. Talk it out and take detailed notes of what they need. Since by now you have a general idea of how long it takes you to get each service you offer done, you can get back to them within a day to let them know how many hours it will take at your hourly rate. You can also give them a completion date if they haven't given you one.
Since you should really be able to give an accurate quote, it's okay to ask for "good faith" money (down payment) at 10-25% of what you quoted. When the client already has money invested, they will be less likely to run away and not pay you in the end.
Make sure that you are available and responsive to your clients. Always respond as promptly as possible. Coming from a fellow student, make sure they know that you are still in school and this is your side business. You have other priorities, but you will do everything you can to make sure that they are your priority just below school.
I could probably go on with this for a long time. I just wanted to outline the basics. Everyone works differently, but this is the method that was recommended to me and what I generally use, depending on the client.
