While I certainly do not consider myself a contractor, I do carpentry work and get all work from referrals.
Often I will meet a prospective client, and just decide I absolutely want no part of trying to make them happy, and decline the work, even if I need the work.
It is their attitude. They basically say they know everything, but just do not want to do it themselves as they are too important, too smart and simply above such menial labor.
Am not saying this is the case with the OP, but when you want someone to do something for you, do not expect that just because you are willing to pay, that they are willing to be subjected to you.
I love being able to decline work. Other peoples projects can turn into nightmares, especially when they do not understand all the intricacies of what is involved or just Poo poo any causes for concern by the person trying to adhere to a design imposed upon them.
I like a challenge, but the challenge must be the project itself, not the person wanting the work done and their Ego.
And bidding on a job is a nightmare. It can take hours just to come up with a bid, and only have 50% confidence that the bid will come anywhere close to actual time and labor. When I know I am just another person making a bid on a project, and that the project owner is just going to take the cheapest at any cost bid, I decline, I am not wasting my time, or subjecting myself to such a person.
