We have a guy in our center who has his own lawnmower repair business. He does his preload work then goes to his appointments. He has contracts with Aaron's and a few other places which pay pretty good. He showed me a check for a repair that he did that was $230. It took him 45 minutes each way of travel and 15 minutes to fix the issue, but since it was a contract he had with the company, they had to pay him some over the top number. He was saying how he cleared over $120k last year from this setup of his and how he's going to retire at 45 years old. He's only 37 now.
Me personally, I don't have a second job as I stay at home with my child after work while my lady goes to work. That should change here pretty soon with season starting as I'll put her into daycare and find a second job by the end of January. Not sure yet what it'll be, but we'll make it work.
