I'm wondering if anyone knows of good sources of graphics for business apps. When I say "good", I mean graphics that fit will with a business theme. I can find all sorts of free sites with nifty graphics, but palm trees and pink flamingos just don't convey "Expense Report" very well.

The graphics don't necessarily need to be free (although ideal), a set of royalty-free graphics available for purchase would work well too. I'm not sure what free-lance artists usually charge, but for small applications spending a few hundred or thousand dollars seems a little steep.

Thanks for any tips,
