Need mock-ups easy stuff

Here is the deal, I need some t-shirt mock-ups done. I have 10 t-shirt designs already done and I need a graphic designer to take each design and mock it up on a t-shirt in various different color combinations. I can provide a t-shirt for you to use to mock them up. Must be very good with photoshop, so that it does not look like it was mock-uped, but looks like the actual t-shirt. I will send over the 10 designs to the winner. Thanks
