Web hosting/promotion

I have just finished a small website and am wondering how i go about publishing it on the net.

My current ISP allows me to have my own web space but not my own domain name, does anyone know of any good web hosting companies and how much it is likely to cost me?

Also im not too sure about promoting my site, i understand i can include certain words in the <meta> tags in the head of the document but im sure i need to do something else in order for search engines to find my site.

Any advice would be appreciated.

My own sites are hosted by:

http://www.easily.co.uk

Which I have used for over 2 years now and find they are VERY GOOD !!

You can purchase a year's hosting starting at £35.00 UK which includes 5GB of Data Transfer.

And This Data Transfer can be carried over when you renew your site for another year, which means that your second years hosting can be as low as £19.99UK !!

You also get FREE stats from which you can get a tremendous amount of info.

For someone starting out it is ideal !!

I would also recommend that you purchase your Domain name from the same company, in that way your site can be up and running in no time !
