I seem to have lost my bookmarked website. Anyways I was talking to some guy that was hired to service a sliding gate in my neighbourhood. He was so nice that he directed me to a different company than his and told me that's where his company gets their supplies from so will be cheaper. Also whenever the other company does installs, they will only do it the right way, which is dig and pour concrete.
I THINK this is the company
PowerGate Access Systems - Access Control & Automation
Perhaps call them up and see if they'll do the concrete work?
