Dishnetwork and bell expressvu use the same nagra 2 software how ever they use diffrent keys the onlything that changes in the process of setting up the dish and the receivers is rather then pointing your dish at nimiq one and useing a single LNB you will want to get a dish with 2 lnb's with pre spaced for "110" and "119" a great site for pointing your dish is http://www.dishpointer.com/ 110 is echostar 8,10 and 119 is echostar 7
somthing like this

you don't have to hit both birds but if you want more channels you should ..
the other change is when doing the receiver setup instead of selecting nimiq 1 select echostar 8 and 10 if your pointing at 110 or echostar 7 if 119
and instead of inserting the BEV keys you input the Dish keys
so basically
- Need to point dish at 110 or 119
- need to select dishnet birds rather bev
- instead of inputing bev keys input DN keys
Thats it thats all
