I have been using Photoshop for, well, forever it seems. Can I make a recommendation?

In Photoshop, go into Image > Adjustment > Levels and a window will open that shows a wave graph with three arrows at the bottom of it, a black one, a gray one and a white one, in that order. Adjust the Input levels by bringing the black arrow to the right to where the wave begins, and the white arrow to the left where the wave ends on that side. Also play with adjusting the Output levels.

I find in a lot of cases this is all you need for adjusting the contrast and color correction. Of course, hiring someone who actually knows what he's doing means you will be able to do a lot more to improve your images.
