I like #4, #5, #3: They all look very professional, but can we get sports worked into them a little more? Thank you very much. #9: I dont really like the dollar sign in the tree logo.
I'm trying to keep the design as simple as possible as you also want to use it on print materials. I do avoid very small elements there and it might look not clean when printed. It this case you can be sure that the logo will print well, and also the symbol might work perfectly as an application icon. Hope you like it.
