Rehab Estimate Template/App/Program Desired

[Jonathan Jenkins]

I work as the acquisitions guy for several flippers/rehabbers and I am looking for a more professional tool to help develop rough rehab budgets. I have created a simple excel template that I update with what is needed to be replaced/updated and it will tell me a rough budget for the rehab. 

I believe there probably are Apps, websites, programs, or better templates for making these projections than mine. Does anyone have any app or program or site to recommend for this?

Free programs are preferred.

Thanks
