Wow Emoish--I don't know how good/bad you are, but you are seriously under-selling yourself (unless your work looks like it was done by a 2-year-old, in which case I guess $50 isn't bad).

I don't have a "price list," because I feel that no two clients will ever ask for the same exact website, even if they ask for the same amount of pages. I first collect details from the client, then I consider approximately how long it will take me, how much the client can afford, and then I come up with an estimate.

But just for comparison's sake, I'd charge roughly $600 for a 5-page site with simple PHP navigation and a contact form.
