What kind of internet prices can you find for the package of three receivers, HDTV and PVR as a self-install versus with an installation? If the difference is large, then it is worth contracting out the installation directly, but if the difference is small, then you'd be ahead of the game taking your chances with whomever shows up to install the equipment. Then, for an additional hundred bucks or so, you could have someone come out and undo a mess, if the arranged installation is in some way defective
If some internet retailer will sell them to you under those terms more favorably than if their sale included an installation, give me a call and I'll connect you with a local installer with a track record, so you can figure out if its cheaper to do it by paying an installer separately. I'm willing to bet, however, that it will be cheaper for you to take your chances with the subsidized installation by the theretofore unknown installer.
I don't have any local contacts for independent local Echostar dealers who could both sell you the equipment and install it. The only ones I used to give referrals to were not very reliable so all I do now is advise people to the hardware cheap on the internet, and then I direct them to a local installer if they are dissatisfied with the installation terms they have been offered. The markup and commissions on Dish network products is just too small for many of the more reputable installation companies to bother with, so most are indifferent to even returning calls, since the caller is a shopper who likely has already had a lower price offered to him elsewhere.
My phone number is in your Yellow Pages under Antenna Alternatives. Once you have gathered enough hardware price information, you can give me a call and I'll try to connect you with an installer.
