Well I would be looking for 2 issues:
1. How they run the cables from the Dish to the recievers. I personally ran the cables myself (Got a 500' spool of RG6 cable from Loewes and spent some time getting it right). I did not put the ends on, I let them do that when they got here.
2. How well they point the dish. On a clear day the 301 should show 110+ on most transponders for 119, and 100+ on 110. Note that they rescaled the 721 to only go to 100, so I do not know what a good 721 signal should be. This is the only part of the installation that is hard because they have to tilt the dish just right to get max signal on both satellites.
Essentially that is it to the installation. They mount the dish on the wall outside, the run the cables from there to the boxes (note the 721 needs 2 cables since it has two tuners), ground the system, plug in the boxes, have them download the latest software, and call your activation into Dish (your smartcard and reciever numbers).
