Boat/RV Self Storage Joint Venture

We have plans that are currently being tweaked to build a boat/Rv self storage facility 1.5 miles away from the main boat ramp near a popular lake. This is on 4.2 acres with 152 units and 65,100 covered sqft (this will most likely change) 

We are considering finding a partner and creating a JV. This is our first deal and we have no experience but the numbers look great and the demand is there.

What is the best route to finding a partner? I know this deal may be too small for some developers but I would prefer to partner with someone that has experience. I am confident I can get the funds from friends/family but I hear that isn't always the best route on your first development.
