I need someone who is pro at EXCEL

I run my own personal training business and I am needing to hire someone who can create me multiple excel templates that work on drop down boxes for ease of use and also calculate weight from any clients max weights. I do have a few videos explaining more about how i need these documents to flow and work.

These templates all need to represent different types of training variables and routines and I can work with you on how I would the layout to look like.
