I took a class in logo design some decades ago, and the best advice from that class was this --

Get a sheet of paper and a black sharpie pen. Sketch out quickly as many postage-stamp-sized designs as you can think of. Doesn't matter if you think the idea is crap before it leaves your brain -- DRAW IT ANYWAY.

After you've got a page of crappy thumbnails, you'll have a much better idea of what you want your logo to be.
