Amateur rock collector looking for rock identification?

I have a number of rocks and minerals that I've gotten from a bucket of rocks that I ordered from Gem Mountain.

I've bought books, but I'm having trouble identifying a lot of them since there's such a wide variety of colors and shapes.

Does anyone know of someplace in Northeastern Illinois/Southeast Wisconsin area that I could take these to and have them identified for me? I'd also be willing to consider on-line places, but I know it's a difficult working from just a picture.

Thank you!
