Take a look at Robert Johnson, Elmore James, and T-Bone Walker. Bluesman in that vein all tend to have a style that I think you might enjoy. All of them have their own way about them, but are some of my favorite bluesman.

I will say that if you want to have a lot of fun with acoustic blues, look into learning a bit of stuff in the way of the shuffle.
