Help!

....Does anyone out there know of any good web design short courses. For the longest time I've been trying to find the right course to enroll on, but none of the one's I'm finding seem to meet with my very special criteria... Which is that it is a short course (evening or day, not fussed), but that it be focused on using dreamweaver...I'm quite good with HTML, so I guess I have some basic foundations...Oh, and that it costs less than £470... unfortunately I'm not that minted, LCC! If anyone has any insider knowledge of the web design kind please share it with me, I'll be most grateful...

Sadly the plans and designs I have been making for my new webpage are far more advanced than my skills on the computer!
