Excel and VBA Expert for Nutrition Calculator

Hello, I'm looking for someone to help me put together a nutrition calculator. This is not like any nutrition calculator you can find on the internet and it is pretty complex. So I will need drop downs and sliders built into the excel sheet. The calculator will calculate the number of calories an individual will need to consume for fat loss or muscle building. It will also break down the calories into macronutrients (protiens, fats, and carbs). I will also need it protected so anyone who downloads it does not see or steal the formulas I have created. Understanding nutrition and having knowledge about energy requirements for the body is not required but highly recommended. NDA is Required before starting project.
