Muddawg, I say more power to any beekeeper willing to go get free bees. The money part comes in from the cases where the bees are in a particular spot that scares the pants off of your average beekeeper. When the local beekeepers come and look at it and then never show up again, then you have a job. Usually involves heights and sometimes high voltage. Every once in a while it involves close proximity to expensive things that break easily.
Absolutley, most beeks long about their third or fourth year get to feeling their oats and set out to become as regular bee empire and chase every swarm they can and the really froggy see something on youtube about cut outs and trap outs and away they go chasing "free bees". By their fifth or sixth year they realize like the rest of us have that there ain't no such thing as free bees.
Those that last learn to put a price tag on it or quit doing everything but swarms and if they really do become a bee empire they lose the time to chase swarms.
I'll go out on a limb here and say that money can be made in bees you just have to learn your niche and mine is cut outs and trapouts. And I'm doing so as the president of a 100+ family bee club and I give classes every year on what I do to those who would do the "free bees" and I'm still busy.
