Hang in there and don't give up hope. Sorry that I don't have one to offer you, but my single hive has been trying to make a queen since the end of Feb. Multiple failures on queen cells and getting a mated queen back to the hive. I bought 3 frames of eggs from a beekeeper and only 1 "took" (meaning they got fed and turned into capped larvae by the workers). Had a newly hatched virgin in the hive at that time, so they didn't try and turn any into a queen cell. Now I don't think the queen made it back from her mating flight. Oh, the wonderful world of bees...
This guy posted a few weeks back that he had some for sale
