need on-site installaton in Markham
 

Hi, I am looking for an experienced mobile technician with qualified work, who can come to my place (Warden and Steeles in Markham) to install back up camera, and remote starter. Please send message. thanks

Free bump ... I think a shop is going to be your best bet or maybe even a Kijiji post.
There's people who advertise that they do this stuff in Toronto but I don't know how mobile they are ... take a quick search there in the services and what not.
Put up a wanted ad.

I know there's shops in Markham though. Audio Heaven is Markham, is it not?
