Believe it of not, taichi, there are plenty of of good, conscientious tradesmen around. Finding one can be fraught, as you know.
I have to agree with ummmm, personal experience or recommendation is the best way. Easy to say, I know.
You shouldn't have to plead, or adopt an attitude. It sounds like a nice job for someone. It's a slog, but, asking around for recommendations will surely result in finding the right people for the job.
No need to get desperate though. Take your time and you'll get there. I just wish I could help make it easier for you. Good luck.
