HippieLizards, with as many mouths to feed as you've got, I'd definitely be farming my own dubias (and probably mealies and/or supes too), but you know your situation best.
A while back I got/had the idea of a "feeder co-op"; a bunch of reptile keepers (who can stand each other :roll: ) raising feeders & sharing the workload like other co-ops. Costs would be apportioned. The feeders wouldn't be free, but should be far less than from a commercial vendor.
Yeah, I've belonged to co-ops before, so I'm aware of the pitfalls. :wink: Finding the right group of folks is paramount (and nigh impossible). Might work for a local reptile club. :dontknow:
