On the thread note however, I would be careful of doing the entire operation "under the table" that is just asking for problems. Also, having your employees handle their own equipment etc. is problematic in that they literally have everything they need to not need you because they have it all themselves. Seems it would be a very high poach rate. I thought you would provide the equipment necessary, something that they would need you for to do the work. That would be your value to them.
