My best customer has fallen on some hard times (business down and devoice) and has not been able to pay the balance on the three mounts I did for him. I've done dozens of mounts for him over the years and for all I know I'm one of the reasons for his divorce. I've had them completed for six months. I've contacted him a few times and feel for his situation and I don't want to alienate him by getting too pushy. Besides doing lots of work for him he's also referred many other people to me. I could legally just sell the mounts at this point, but I know that if I did that, then it would certainly cost me business down the road. I'm not hurting for money but my studio space is limited and with the fall rush comming up, I need to make a decision on what to do. These are three very bucks that would fetch more than enough to pay the remaining 50% balance due, plus late fees owed. Any suggestions will be appreciated.
