All great ideas on your situation.
I also can suggest a few things that have put me off starting a job.
I take the time off from making money and show up to hear "we want your ideas on how to fix this".
We need three differnt quotes for three differnt ways of doing this job.
I need you to start this job tommorrow.
(Anyone that can do it that fast is out of work for a reason)
I'm not willing to pay (at least) for the materials until the jobs done.
I just want to cover up all the rotten wood so I can sell the house)
I'll supply the labor you just show up and tell them what to do.
"I do not care to hear what the right way to fix it is, this is the way I want you to do it.
I do not want to pay for a helper, just you. (this was heard when I had to replace rotted 27' rake boards on a three story house).
One job was to replace one piece of coil stock on a three story house at the peak that's 30 min from my house. I quoted $250.00 and they said I was ripping them off. Two people 3 hours labor, having to stop what I was doing to load all the equipment, showing up with $2000.00 worth of equipment, $1500.00 trailer, $25,000 truck, and have to climb a 40 ft. ladder.
Two years later and it's still not fixed, now there looking for someone to replace the rotted wood and install the coil stock. Ha Ha.
Where all stupid, just in different subjects.
