I contacted John because i saw so many good review from WOMO. Glad to Say that i'm Very Happy with John. Not Only he is friendly, he is Also Very informative. He told me that The switchboard needed to be upgraded for safety reason, however decision is all mine.
So i ended up getting 2 PowerPoint Installed and an upgraded switchboard.
I Will definitely use his Service again in the future!

Approximate cost: $1000
