Customer has $20450 contract, and owes us $10571.09. We opted to no file a mechanics lien because we thought the customer would pay, but they didn't. Now we're in a situation where we can't file a lien. We could possibly try to get this settled in small claims court but not sure what the limits are, try to submit to a collections company but not sure what options we have. Customer isn't returned any calls or emails.
