I live in UK but using webhost from US which are much cheaper and good quality.

There are many good webhosting sites.

Visit

http://www.nicewebhosts.com

there you will find best web hosting providers compared with their webspace and bandwidth as well as their prices.

Hope you find the right one.

Check MyWebbieHosting.com. They have servers in the US and UK, and their plans are very affordable. Lowest plan costs only $3.95/month, but it already includes 1.5 G disk space, 150 G bandwidth, 50 email accounts, etc.

Besides, if you register a domain name, the first year is free if you sign up with one of their hosting plans.

However, I'm not sure if they have Sharepoint server. Try contacting them, their support will respond to your inquiries.
