Design some Icons

Hello - A buddy of mine would like some sprite-sheets, images and icons for a video game concept we're putting together as a hobby. I'm the Lead Programmer writing a Puzzle Game that we invented on paper and are now trying to make it digital. I'm targeting Linux, Windows, Android and iOS via C++ and need assets that can drive the theme so I'm looking for the following: 1. A Theme look-and-feel for this puzzle game. Something Orange and White or Blue and White, or any other color combinations you think are great. I'm very open minded on the design so please share your creativity. 2. Button Designs in various sizes for different screen resolutions. Please make the same button for high definition and low definition devices. The button design should allow for text to be placed on it via PhotoShop or some other professional image editing tool. 3. Create a 5 x 6 grid both in high quality and low quality. The grid should have some depth to it and match the overall theme. 4. The grid can be filled with circles or boxes of various colors. Please design a circle and square that can fit inside one of the grid cells both in high quality and low quality. 5. Lastly, I need a logo that's fitting for a puzzle game such as this. Please bring your creativity to the table because I definitely don't have it in this area =). I'm looking to have assets as soon as possible and would prefer someone who has designed graphics for games before. If you don't know what the term "Sprite Sheet" is then I don't think you'll be a good fit. I have an open budget and with the right person I'd be willing to pay upwards of $1,000++ for future projects and games that I'm planning to design. If it all works out well I'm looking to hire someone for top dollar ($60/hr) to do private design work for me on an on-going basis. Thanks, Happy Bidding.
