Business Logo design needed

5 Business logos are needed. All with simple & contemporary design. 2 of the logos will be identical designs and only different names, and another 2 will be same/similar designs just different names. So basically will only be 3 different designs. I will need to see a portfolio of your work and once I reply to you I'll want to see a mock-up of one of the logos before I choose who to award the project to. Designs must be available in PNG format and if possible vector format so they can be resized for different publications. You must continue to revise your designs until I am 100% happy with them. Bidding on this project means you agree to giving up all intellectual rights to the designs once the project has been completed and paid for. The designs will be the sole property and intellectual rights of myself. I'm willing to pay a maximum of $30 for these 5 simple logos.
