Installation pricing

[xboxhaxorz]

I have a friend who wants me to install x10 in his home. He wants 6 wireless cameras and a alarm system installed. I have done the single camera motion sensor for my front door and other misc stuff but i am not sure how much to charge for this type of work. I mostly do IT repair, but since this is new to me i dont really know.

I would also have to get a friend to help with the mounting of cameras since i am just a techy. My friend does home improvement so he would pretty much mount the cameras and alarm systems.

I am sure most of you have installed it yourself, but if some of you have had installers how much did they charge approximately?
