How many hours will it take you to make the first five pages? (where most of the design effort goes). What do you want to earn per hour? That's your minimum starting figure (whether its 2, 4, or 5 pages). Scaling up to bigger sites, some people charge by the page, others by the hour. Large sites can involve two or three sections with different features, so sometimes extra pages will be at a similar rate to the initial pages, but extra pages with an identical layout are usually a little bit cheaper (just a little bit, not a lot) Maintenance is usually by the hour - I have an editing rate for existing pages (easy money, it's just typing) and a higher rate for creating new pages. It's all up to you.
