I had one built two years ago. Had quotes from DU and LMDC. DU was slightly cheaper, but they had a job nearby and could start right away. DU did a great job and the remote control lift has been a great addition, especially docking in windy conditions. When pricing be sure to compare materials and specs. I visited a friend who bought on price and his dock/lift looks very dinky compared to mine. He has mentioned this several times. 

Heres the spec sheet from DU:
