Get talking to your local BKA members - now.
You have some hives? If so talk about attracting a swarm or two.
I am sure one of the members would be able to supply some old (but healthy) comb as bait. Add a swarm lure and cross your fingers in the swarming season. But you have to take what you get - health, demeanor etc., that way.
It might be as cheap to buy a local nuc from one of the members (rather than do the course 5 more times!!).
You might be brave enough to get your name on the local police/council/pest control lists and collect a swarm or two if the opportunity arises.
Lots of (well several!) options. You just need to list everything, decide on what you are willing to do and get on with it.
Probability is you will get more than you want/need, by actioning several options, but nothing if you do nothing. Sounds like there will be takers if you get too many, and you would be an instant friend to anyone who gets their first nuc/swarm through your efforts.
