It is a significant sum for some but you would have to also purchase a reliable vehicle to travel nationwide. Only 25 days holiday and weekend working if required. By the sound of it there would be very little time to do you own beekeeping.
If someone really wants to beekeep all week and earn that sort of money why not set up a small beekeeping company and work for yourself. Last year I earned approx 60% of that salary working on average 2 days/week and never had to travel more than about 10miles from my front door.
I only had SWMBO pressurising me, (mostly because I should be spending more time with her now I'm retired), could plan my days around leisure and the bees and the only real extra paperwork is invoicing and VMD forms!
A doddle compared with the NBU job.
