one of the first properties i bid and landed is now at the end of his pre-paid 10 (ten) mow installment. the problem.i didn't get a written contract with the guy,and it takes about an hour to do.the original deal was 37.00 to mow and trim. now that i'm getting busier and better in the bidding dept. i'm thinking about bumping him to 59.00 for the next ten mows. and the guy has been a pain in the a** about things.calls one or two times after he gets off work and bitc*** about something then calls me back and says he sorry etc..... in other words he 's a PITA: ) and out of the way by about 5 (five) mi. any words of ???????
