I would imagine that DirecTV or its local representative now has a customer file for this blown installation in which the installer gave his reason for declining to perform the installation, such that he would qualify for his "kill" fee or otherwise avoid getting fired.
If you want to give it one more shot, you can call DirecTV and explain what happened and tell them the estimated cable lengths and see if they will send someone out with foreknowledge of that obstacle to installation. Since I am not a residential installer, I do not have current knowledge of any exact maximum cable length that DirecTV will sanction as part of their standard, "free" professional installation or that they will permit as a customer approved "custom installation", but they must have such standards, otherwise, they could get unwittingly sucked into having to either perform installations that cannot be expediently completed under the terms they have with their installers or supporting installations that they do not consider to be technically valid.
It sounds to me like this installation can readily and reliably be supported by a single line SWiM installation using RG-6 coax, since an SWM installlation can simultaneously support up to eight tuners. One downside of using SWiM over long distances is that there is usually a little more structural signal loss with SWiM than there is with a multiswitch system since multiswitches tend to be designed as "zero loss' components, whereas the splitters used in SWiM systems lose about 5 dB per two-way split or 10 dB per four-way split, at the upper frequencies. On the other hand, it has been reported here that the SWiM LNB does have automatic gain control whereas the four-wire "wideband" downlead system does not.
Either way, your cable lengths do not introduce structural losses that would be of concern to me. It looks to me like a simple economic problem. When I installed C-band for a company owned by a mafia mobster, we were paid a flat $300 labor for an installation, no matter what, but on the east coast, we had to be able to target the western satellite arc down to under 20 degrees of elevation, and since most of our customers were in the woods, sometimes moving the dish another hundred feet away got you one more satellite on the lower arc, but the labor involved in burying a 500 foot coax even a few inches below the ground made it a dealbuster for the installer.
If DirecTV won't pre-authorize an installation on dish as far away as this one is, you can get the hardware delivered to you by an internet dealer and self install it, or at least, self install the coax if you are not technically proficient enough to connect and peak the dish yourself. You can still have their installer peak the dish for you as part of the free installation. If you run your own coax, just remember to buy direct burial coax, with a solid copper center conductor. And it is a good practice to run a spare coax or two, just so if one or more get damaged, you won't have to trench again.
