I hired Joe to pour a 50x30 concrete slab. I paid him 1/3 upfront. He worked a few afternoons and didn't return for a few weeks with no communication. I called a professional and I am so glad I did. His forms were out of square by NINE inches and one corner would have been a FOOT lower. I lost every bit of that money and had to pay for his mistakes. I would not recommend him to anyone for any job.
