how to calculate the after renovation value and get funding from a HML

[Shadrach Palatino]

I was hoping someone could give me a quick step by step guide to determining the value of a home after the renovations, and the best way to present this to a hard money lender.
I know the short answer is to go in and talk to a realtor but I'm not really in a position to buy right now and I'd rather not waste their time.
Also what lenders do you like like to work with?

Thanks in advance.
