This information is too late to help Mikey, but I will post it for future readers that may be in the same predicament.
I just finished rereading an article on laying workers and how to fix it. The article, written by Paul Hizsnyal, appeared in the July 2016 issue of Bee Culture. For this to work the beekeeper needs another strong colony and a strong nuc with a good queen. The time of year could also play a role in success. I wouldn't bother in the fall. Take your losses in the fall.
The instinct for survival is so strong in honey bees that when faced suddenly with a queenless or non laying queen situation, workers can sense the lack of brood pheromone within 24 hours. The workers may attempt to replace her using existing larvae, even using 4 day old larvae. This will result in a small undeveloped queen that is inferior. The new queen faces the usual challenges during mating flights and the colony could still find themselves without a queen and chaos with in the colony begins by workers attempting to lay eggs. Multiple eggs in cells, which are all unfertilized will result in drones. These drones can even be smaller than normal because they were laid in worker cells. The result is definitely a hive that is out of balance with nature.
The suggested fix:
Switch the queenless hive with another queen right colony. When the foragers return to their original location, they will find themselves in a chaotic colony lacking queen pheromone. The foragers will also not find worker brood pheromone. They will restore order with in 48 hours and "eliminate" those pesky laying workers. Drone brood should be scraped out or replace the frames.
Requeening the queenless colony should be done by placing a strong nuc on top of the queenless colony using the newspaper method. Make sure the nuc does not have a entrance and they have to chew and mingle slowly with the queenless colony. Leave the nuc in place, undisturbed, for at least 5 days which will ensure they don't kill the new queen in the nuc.
The population in the laying worker hive will have dwindled through all this chaos. The nuc will replace the lost work force and life should be good again.
This should work under the following conditions. 1. The queenless colony still has a large population. 2. Schedule manipulation during good weather. 3. Start manipulation after 10:00 a.m. when foragers are out of the hive. 4. When introducing a new queen, she should be in a nuc on top without an outside entrance.
