My first one took 5 hours because I had to tear down and redo the existing installation to incorporate this new thing called grounding. I also had to install 2 new recievers, AND play musical dish 1000 (LOS issues+ nobody could tell me the proper elevation for a wing dish hitting 129. They kept spouting dish 1000 numbers. I had to monkey around and come up with that info on my own).
2nd took 3 hours. Again, I had to spec out a self install, convince the customer that the dish 1000 was NOT the answer (again, los issues) AND get him approved for a DPP44 to run 4 orbital locations to 1 lonely 622.
I don't know that I'll do anymore. I found out that we don't get any consideration on the reciever swap out end. That is to say, we get paid the same to do a dish 1000 upgrade with a 622 swap out, as we do for a dish 500 upgrade. Its not really worth my time to do all that AND haggle with customers who have dreams of a 1 dish utopian solution. Then again, if I got some customers who didn't live way out in the woods, I might have had an easier time.
