Unreal Engine Level Designer

I am looking for a level designer to create or enhance 2-3 levels from my current project. It is for a runner/platformer game and is very small scale. Below are some images from some of the levels we have currently. Right now I can only afford up to $50 worth of work. Please only inquire if you have specific experience as a level designer in Unreal and a portfolio I can look at. Any less than that and I will not entertain bids.
