podlod, the price of a site depends on many things. Are you going to create it yourself or get a professional to do it? What will the site consist of. You could get some good hosting for less than £50 per annum and initially put one page up to establish your presence while you're deciding what to do. Try Heart Internet for hosting, they're pretty good. click here
