We have another company we work with that has a bucket truck. 90% of the time we just outsource the install to them and we get a bit of free money just setting it up.
Anytime it's something we want to install rather than contract... We itemize the quote. There's nothing wrong with a $900 quote to hang a banner... Is it high? Sure... Are you screwing the customer over because you didn't mention you could get it down b a guy with a truck for half the price? Not in my eyes.
I don't tell the guy who wants 5000 decals a week he could get them done offset printing for 1/10 the price that I charge to do it digital.

1 hour travel time... XX dollars
30 minutes install time.... XX dollars
Bucket truck rental... $800
If they see the above, they're not going to think you're expensive.... They're going to see you need specialized equipment and that's why the price is so high. Then they can shop around if they want.
If we turned down every job because someome can do it cheaper than us, Billy with a printer in his garage with zero overhead and labor costs would be a millionaire.
