New customers qualify for free installs and free equipment so if this is a legitimate request all he needs to be is a new customer to get free equipment and installs!!!!!
Maybe he was a sub two years ago, so he can't get the new customer deals.
To address the original question, call around your local satellite dealers and get prices from them. They can help you determine what you need and what it'll cost.

The post was edited by the OP after I posted my responce. He wanted to get a receiver with the 120 + a couple ethnic channels and add a couple receivers "for my neighbor buddy because then its only $5 an extra box". He also wanted to get 2 or 3 Dish 500's
