The money is in the wood at the retail side, and that

is not easy unless you are in the business, limited interest. 

If selling you need a contract about time of entry for removal, that means when they need to start and complete the project.  You have liability during this time.  I would advise getting paid up front for the entire amount you agree upon. 

This will involve your insurance agent, and you may need

an atty. for consult, and contract, that is several $100. 

Decide if it is worth it.
