Thanks for the input. I'll probably quote her $300 for the removal, then $75 an hour over 4 hours. I know it's less than you charge, but I think you have much more experience, and theoretically can move much faster at it. If it ends up being 4.5 or 5 hours, I'll likely just keep it at the $300, but won't tell her that till I'm done.
I'll let her know the quote, and see where it goes. I'll be in touch about borrowing a ladder and/or a bee vac. Thanks so much for the help.
