Can you hire friends in the trade?

Since you are trading out of vacant land, you are looking to dump an asset that didn't require much management. 

@Gladys Cepeda there are merits and trade-offs to both approach.

Facebook marketplace or even a "buy/sell/trade" group within Facebook could be a great spot. 

You may get some people off the bat who won't want to take on the project.I'd also recommend having a timeline in mind for how quickly you want to get the project done and asking each contractor if they have other trades they have experience working with and like working with. 

I'll trade you!

It's also a lot of risk if you don't have relationships with builders and other trades and understand how to navigate the local permit process.

Thank you for the response; I will propose a cash-for-keys trade-off.

Trades can be a great way to do that.

I used to work for a utility in operations, power generation, energy trading and in Strategic planning, and know just enough about the electrical grid to be dangerous.Renewables are a significantly larger impact than when I was working in the business.
