Easy money!!

I went to a warehouse in Indianapolis to build a barn door along side other people. We were given materials and the wood was already measured out for us. We bought a barn door before going there but it ended up being to big so we payed $100 to build our own at this place. The neighborhood around the place was pretty sketchy but the people were really nice. It took about 2 hours to get it almost completed but I had a basketball game so we had to leave early. Looking back I thought how much the lady made doing this and it seemed to be a lot. All she had to do was buy $40 worth of supplies measure and cut the wood and that was it. She charged $100 and she Did this about 3 times a week. With 12 people usually coming in having two on a door she was making around $1080 dollars a week for basically doing nothing.
