Been trying to figure out a cost effective way I can buy the large 55gal drums of the two main components and all the gear for spraying for this reason as well trying to cut my cost if I do all the work. Cheapest I have found was a complete ready to spray trailer set for 20K. BUT I have 2 quotes to do my house, one was 12K the other 14K.

SO do I buy the RTG trailer set up do all the work my self and then try to sell the unit, or just spend the 12K

Pay the man , that is some nasty stuff to work with . There is a lot more to just mixing and spraying . You have to pay attention to the temps of the wall you are applying it to . IF you go the open cell route n fill the wall cavity make sure all of your low voltage is secured tightly because when that foam expands it pushes the wires out and the guy trimming the excess off can easily nick that thin LV wire for alarms , av etc . And you wouldn't know until you try to get it working after you move in
