I wanted 3 LAN points installed in my two story house. The first electrician I called said it couldn't be done and that was that. I decided to give it one more go and called Andrew's. They came out the next day and also said it couldn't be done. But they didn't stop there. They spent a good half hour crawling around the roof cavity until they came up with a solution. I got my 3 LAN points without compromising in the slightest.
I have no trouble recommending these guys for any electrical service you need doing.

Approximate cost: $650
