Remember to have insurance, as required to protect you, the sellers while you are on their property, any and all workers, your vehicles, tools and equipment, including rentals.
Have a plan, keep the site organized and clean as you progress. SAFETY FIRST. The more experienced your team and how well you communicate will have very positive influence on your safety and efficiency.
I like a big all-terrain forklift w extendable boom. If barn is very tall a crane may be much better for the high-up timbers. You don't want the crane operator waiting idle while one or two guys are struggling with some ornery tight pegs. Crane time is very expensive.
I won't say good luck 'cause luck only has to do with the weather. Be smart, be organized, be safe. Nothing suceeds like success.
