If I were you I'd try this fella.

He's very good, I got 1 nuc and 1 colony off him last week, the bees are brilliant workers, maybe cos they're working on rape at the moment and it's coming to an end. He's only 20 miles from K. L. and a very nice and helpful chap and I know he's got at least 2 nuc's left.
There's no other bees around where I live and I had to super the colony after 2 days they're working so much, the Nuc I got as a 4 frame and they'd nearly filled 3 frames after 3 days in the brood box so I've super'd that as well as I'm away working.
I hope he's got something left for you !
