Advanced USACO Solver in Multiple Languages

I am seeking an experienced competitive programmer to write three solutions for a three competitive programming problems. The solutions should be written in Java, Python, or C++ and should be efficient and well-written. The problems are USACO Gold problems, and can be found at the website http://usaco.org.

This is a one-time job and will require around 4 hours of work. I will send problems to bidders to gauge experience.

My budget is $60 however this can be negotiated. Real people preferred (I'll sift out the bots).
