If you provide a scope of what you are demo-ing, you may have better luck with someone's experience to comment here, but costs can vary regionally, so a local contractor would give you the best actual estimate. 

I live in NYC, I'd like to connect and meet with people locally, partners to work with and groups to join.

I am a local broker, investor and contractor in Memphis.

One way would be to reach out to your local real estate investment club or check with other investors in your area for recommendations.

Funding came from a small local bank here in Memphis, Tn How did you add value to the deal?

If your lease is silent on it, it would default to your local or state statute. 

You want to be local for those I would assume.

Happy to share some insights and connect you with anyone locally.

@Kristen DolotinaYES 100% a service like that existsSpeaking from experienceI had an out of state investor purchase a duplex in Texas & after closing the PM company handled the applications, screenings, placement of tenants for a 1 months rent fee.MY SUGGESTION:Google a local Real Estate Brokerage and call that number and just ask the person at the front desk (who answers the phone) who their recommendation is for a PM company and why.

Hey Alison,I am a local investor/lender in the area.
