I've been told that might take as long as a month.
Good luck and prayers for a quick and fair resolution.
A course to consider would be to photograph everything, ask the power company to restore the private secondary line and restore temporary service — this would take an electrical contractor on your end. The power company line clearance team may cut the tree and not remove it.
Then get a tree removal company to take the remains and call a local contractor to secure the house for later repair — get someone local rather than a traveling crew.
