We live in an unincorporated part of Palm Beach county... about 2 miles from the end of the major East/West road that leads toward town. After that it's swampland and nothingness. So, I expect our power could be among the last in the area to get restored.
When I spoke with the HOA about what they need, I was told that several folks have been doing this, so yes, finding others and talking to them is a good idea. I know of one neighbor who has a gigantic unit on his house... it looks like and industrial unit. I think he's a retired NFL guy so money isn't a big deal for him...he has the best maintained house in the whole place.
Good luck with whatever you decide to do. The 10 days or so is probably a good
estimate to get most of the utility power back online. But the next question
becomes at what stage can the home owner connect back to the grid to use the
power. It make take weeks for homes to be repaired so they can use the power.
