If you want people who are clearly challenged professionally, and down right terrible at everything they do, then go for it! Also imagine only have one other review from the son who is a partial owner in the 'business'. Ugh.

Great people to work with, value for money, very professional, and when an issue arose due to a supplier's problem, they could step up to the plate and assist with finding a suitable replacement, would recommend them in a heartbeat. I have worked with them on more than a few occasions. I can say the people they employ are professionals, and the management team makes anyone working with them welcome.
