Why would the billionaire in question even be concerning himself with the transportation of some machinery? This decision would be taken by whoever was in charge of the excavation.
I'd have to agree. Just tell someone "there is a fully functional digger down, it's free, but you have to get it out."
Hell, people will come and haul away scrap steel from the bottom of a lake. A digger worth $10,000? 4 guys and 8 hours and each of them just made $2500 for a day's work.
