You can pick up domains for about £10 give or take. Web design isn't as easy as some programs would have you believe.
You'd probably be best using something like Wordpress, which is a blog based content management system and quickly learning that. Dreamweaver is the industry standard for Wysiwyg site building, but the learning curve is quite steep.
You could try NVU, which is painfully easy. The code always used to be shit, but it'll do the job and is probably the easiest out of the box solution imo.
You could also find yourself a free CSS template and edit that in an editor, that'll give you quite nice code and a basis and framework within which to build a decent enough site.
Edit: Wordpress isn't a great idea, go with NVU and a free css template. You could do it in no time.
