I would have required that a professional install it.

I had them installed during the remodel up there.The first floor where my wife and I currently occupy is also recently updated with a new kitchen, all new appliances and is also a 2 bedroom with a fully finished basement.

Keep in mind, you will likely have to install a sprinkler system, among making other changes for the home to be used for that purpose.

I know someone who installs security systems.

After a thorough review of systems, we had plumbers troubleshoot and repair/replace a couple of small chronic bathroom leak issues, and electricians installed a number of end-runs back to the panels so that rooms could each have window A/Cs running without tripping circuits and other such issue.

I’ve found that as long as they’re somewhat insulated and well installed the color won’t matter.

I tried to estimate what a GC might cost in my calculations, but I have an uncle who does roofing and cousins with window installation and landscaping businesses, so I believe I can save some significant costs through their help and guidance. 

In a lot of cases, there was a drainage system installed but it was not properly maintained and therefore doesn't work. 

There were a few other things I believe which are destroyed including carpet which was newly installed a week before she moved in, but b/c it is 7 years, I can't do anything about it from what I read on this forum and other people asking these questions. 

Since then, he has had to replace the windows (the seals got old) and now he has to install all new plumbing.
