Joe, Years ago, we would take a contract for restoration, over the phone. No deposit needed. Never knowing the person nor their ability to make good? We got burned with a couple of units that the deadbeats, changed their minds on. Since no money had changed hands, they didn't care that we had put out funds and labor to build the pumps specifically to their liking. The pumps were eventually sold but the lesson was learned. Now we take a non-refundable deposit up front. Never had a problem since. Your choice is one that keeps everyone on a level playing field. Good move. Paul www.severngaspumps.com
