Hey, Dogfaceboy in order for me to grant this contest I will need a few things from you first...
Firstly, is the contest $100 or $150? It needs to be clear, secondly I will require a $50 deposit on this contest (reason being, you originally stated you didn't want to pick a design if they're weren't any you liked).
I feel this is the only way I can ensure you're a legit user who wishes to run a succesful contest and not a scammer, like we have had here before. I hope you understand my reasons behind this. This would basically mean, I would pay the winner $50 and you would foot the rest of the bill.
Feel free to check in the "finished contests" forum for examples of previous contests. The impression I got from your original post didn't convince me enough to approve this, therefore I need a downpayment.
Sorry Rob I know I shouldn't post this here because it is not the place to but if you are going to take DogFaceBoy up on that and e-mail him my advice is ask for a deposit!
