Design new Wordpress theme - basic for GNU

I would like to commission the creation of one (1) original wordpress theme to be distributed freely with GNU. It will be posted on [login to view URL] and other free theme locations. The design should be interesting but basic. I don't want fancy design with integrated widgets, etc, etc. Just good basic theme for wordpress 3.x . It must be original and not look much like other themes. The theme will be used to promote our business and build back links, so design credit will be ours. If you can encrypt the footer link without a lot of cost, I would prefer that. If it costs much more, I am not interested. These will not be sold for profit and we will retain all rights for distribution. In other words, once they are paid for, we own it and the provider cannot use it without permission. Please show your experience/ portfolio and offer a good price. 50% up front payment, 50% when complete. Freelancer milestone/ escrow only.
