I wouldn't be so discouraged, keep in mind that it takes 3 days for the queens wings to age/cure enough for a mating flight.
However those are usually 3 days you're using to get her introduced.
Hopefully this helps you feel a little less uptight about getting them mated.
I would work dilligently to get them into nucs to begin introduction - possibly by the methods listed above for quickest results.
The books that I have all read give a two week maximum window before the spermatheca fluids harden and mating is impossible.
There is always more than one way to skin a cat, that's of course if you're into eating cats.
