This contractor is fast, responsible, skilled and courteous. He responds to questions and concerns promptly, and is great with communication. His work is superb and his prices are extremely reasonable. My only recommendation is that he improve / upgrade his accounting system to provide email quotes, the ability to pay with a credit card, and to email receipts (I havnt yet gotten my requested receipt). Receipts should be available immediately upon payment, even if in hard copy. I would suggest the "square" for an iphone or ipad.
