Have a real bad feeling about this bid. New customer has been so undecided from the get go,changing and doesn't want to listen. Had reservations about giving the estimate in the first place. However, against my better judgment I gave the estimate,customer wants to start, however, I feel I won't get paid the job. Want to back out, having the contractor "gut" feeling about this one...they call every hour with questions ..very high maintenance...any suggestions? Thanks !
