How Much Should I Charge for a Website? -

I m making a website for someone and I don t know how much I should charge. Its not going to be a crappy one, I m planning to make it mostly in flash, and some of photoshop. the most pages it would have is about 3-5, but still mostly in flash. since its the first time I will be doing it for money, I have no idea what to charge. Please help.

Call people who make web site and ask them how much they charge?
