Omni Pro reference? and hardscape followup

I got quotes for a hardscape project. Greg from Omni Pro was great: prompt, detailed, good price. I have one positive recommendation from a neighbor. Anyone else use Omni Pro? Good or negative experience? We got burned by a waterproofer, so I'm being super careful. The other companies who quoted: *Eichenlab*. Fantastic. Expensive. Would hire them in a second if we could afford. *David LeDonne of Solid Concrete*. Very nice guy. Other recs from neighbors: Paul Gullo "great, hard working, very detail oriented" 412-443-5085 <(412)%20443-5085> Christopher Criscuolo 412-913-6637 <(412)%20913-6637>
