PSD Design for Real Estate Portal

Hello Freelancers, I am looking for a well experienced web designer who can design a PSD for my upcoming real estate portal. It would be one of its own kind product in the online market. Therefore, I would like to hire the one who will sign an NDA, and abide by all the rules set by me. Additionally, I am quite low on the budget, but if I really liked your work, I will offer more work to you on a regular basis, and then we can set the prices accordingly. The one I'll choose will also design a comprehensive logo for my portal. My competitors would be MagicBricks, 99Acres, CommonFloor, iProperty, so while sending me your mockup designs kindly check them properly, and send me something that looks better than these websites. Additionally, I would also like to have your suggestions as well (if you would like to offer). I am short on time, so please be fast with your responses, and don't forget to send your past work, references which can be verified, and a sample mockup which can demonstrate your creativity. Regards,
