I too would say that unless there's lots of hidden goodies then you will struggle to reach the sum you need to. But I know nothing about the frames on offer so could easily be wrong.
I would say your best bet might be to try local Facebook marketplace - perhaps as open to offers. Unfortunately, the urgency of your situation does not put you in a strong negotiating position - and it's a buyers market for anything cycling related at the moment. Maybe it's worth a trip to a local bike shop to ask for advice. They won't be interested themselves, I'd guess, but they might know someone who could be keen.
I know you are looking for a sale as a joblot, but wonder if separating into separate lots of tools, furniture/storage and bikes/parts might help.
