John is the best I have ever worked with: he's very thorough he's always going to give you the very best option. John is very smart if he doesn't have an answer he will figure it out. His prices are unbeatable, the honesty the thoroughness I would be willing to pay almost double for his services!! John has done work for me at my home rental home and the retail business I run . Thank you!
