How can I hire a mathematician or physicist to help me model the orbit of Mercury?

I've developed a rather simple analytical equation that provides the acceleration of gravity caused by a mass on another mass, which is valid for all distance scales. However, I need to find someone who is familiar with mathematical programming or numerical analysis to help me program it. It could probably be done in Mathematica. 15 years ago, I could have done it a few days, but my programming skills aren't what they used to be and I don't have the library of numerical recipes anymore.

I've spent a few years digging into the geometry and the observations to put this together and I have a lot of confidence in it. It provides an explanation of the 1sa supernova data without dark energy and Newtonian level gravity is explained. However, to validate the model, ineed to plot the orbit of Mercury using the model and I'm willing to pay someone even if they prove wrong.
