Creative designer for WordPress (and maybe more)

I have some projects needs to be done: 1. Designing a logo and some pictures for a landing page of a new app. 2. Re-design a WordPress website 3. Transfer some websites (mostly WordPress, 1 Concrete) from godaddy servers to one amazon EC2 server. 4. UI design for a new C# .Net app. I'm looking for someone that is trustable and not expensive so we can work together for long, I have an expanding IT business. If you're skilled for only some of my requirements, that's fine. I might hire different employees in that case. Must be experienced. Please send me links to some of your works so we can proceed.
