I think it would be either an Electrical Engineer or a Physics/Math nerd who has familiarity with Piezo electricity and with the Mac Numbers Application.

I am free range inventor working out of my garage. I am exploring the use of piezo's. I am seriously math challenged so I am looking for someone who can create a calculator for me so that I can key in the variables on my Mac - (Numbers) and have the calculator do the work for me. I am interested in determining the power in watts for certain piezo materials where I can input Force - Length - Width - Thickness, piezo properties and frequency. (Am I missing something?) I am thinking that someone who knows this territory should be able to create a calculator for this in about five minutes. The budget range below says $30 - 250. and it seems to be non-adjustable. I'll give $100 to someone who can create this calculator.
