How to find legit lenders rv glamping site in NY

[Keva Niver]

We are working on our first niche rv park development and would like to avoid scammers. How do you go about this? 

We have the land under contract and already got zoning board approval through a special permit and a variance.

Hoping to avoid silly mistakes.

I'm already getting scam calls and I have no idea how they are finding me.

Advice needed :O)
