i own a little design company called Mcfluffit design (
www.mcfluffit.com)
i dont put all my time into as such as im still a student, but one ting ive learnt is that pricing is absolutely crucial.
Looking at your site you are very cheap in comparison to most as a normal web design would average about £550 ($1000???) for a 6 page website <ish>
However i don't like to charge high prices either as it just sends customers away, so id say your definitely on the right track there. What i would suggest is that when your first in contact with a customer and giving them quotes make sure you make perfectly clear how much work you will do for the set price, for instance dont just say £200 a website as there idea of a website might be much bigger than you thought!
another thing is to charge hosting/maintenance monthly rather than yearly as it really does make the price seem less to the customer and there more likely to return to you in future and you can keep a steady cash flow throughout the year, week by week that way.
i know this is problem obvious stuff and maybe not what you where looking for in terms of advice but i hope i mite have helped.
p.s. i dont mean to sound like i know a lot, i only know a little so this is just my take on it all, im pretty sure my figures are right roughly. Also what uni are you in at Wales? (or at least ur location says wales)...
