Sounds like you're on the right track, cfo.
You might want to double-check with them about the dish install(s)......what constitutes a "free installation" usually means "roof mount". If you want it installed elsewhere, ex. pole mounted in the ground, it's generally an up-charge. And generally you'll get to arm wrestle with the installer over that charge as they're many times independent contractors, not employees of the satellite provider.
