I am interested in your project and know I can create the sprite art for you. If I am correct in reading your project description you need a total of 32 frames total, correct? I know your project budget says $10-30, and I have my offer set at a higher, but still very good price for that amount of work. And if you need a fully working animation, the price would be higher.
I just finished a set of poses for a simple animation similar to what you are wanting. I also can create sprites in an older game style. Older games are created with a "hard pixeling" method. I have some examples of my work in my portfolio here. Feel free to check out my recent updated portfolio entry titled "Pixel Art".
Thank you for your consideration, and if you would like to discuss the details further, feel free to contact me.
