What do you pay for website hosting?

[J]

So I have this idea for a website. I'm going to need unlimited space etc.

I've had a site before, which did well before I shut it down. but that was on a free network.

This time around I'm wanting to look and be more professional.
I've been looking at http://www.ipage.com

I like what they offer but £5+ VAT sounds expensive for an "early days" website.

with this sort of thing, can i cancel it at anytime? or would I have to sign a contract for like 12months?

also if you know of anything cheaper, with all the tools and support and reliability. feel free to share?
