I made over $2K in august, I think that selling websites / templates on forums isn't that profitable and the money is really in the custom work. Small businesses usually pay more than individuals although at the age of 15 you can't really get involved with businesses yet. (Talking about 15 year olds in general, including myself :\ )

And yes.. 200 pounds a week is alot, especially compared to other kids working at Mc Donald's for 3 bucks an hour.

In 3 years you'll be riding your bike and other people will be poor bums *grins*
