Since you would be working up- in -the -air I would be sure what happens if you fall and hurt youself. If you have no experience working at heights you are at a disadvantage, plus dealing with bees.
Are you a contractor with your own insurance protection? Will the property owner cover you as far as workmans comp? Very important considerations here.
Bear in mind that your rich man didn't get that way by being stupid, but, he probably took advantage of stupid people along the way and of course called himself way smart. Then again he might just be " the real stand-up guy ". Hard to say without knowing the " true story ".
Quite frankly, speaking from some experience doing removals, there are way more efficient ways of dealing with bees for hiving, than this foolish scheme. Those bee captures are a real PITA IMO.
Swarms are OK and that is about all I will do anymore.
