Wanting to Install ?
Nick you may want to look around at the link here---

There are a lot of changes going on right now for Installers across the U.S.
If after reading on the site at the link provided you are still interested i would suggest you try to find someone local that you can arrange to get in the field with ,who is already employed as an installer so you can see what things will really be like when you are out in the field yourself.
possibly someone willing to take you on as a helper for a week or so ,before you make any commitment to buying -tools ,insurance and other equipment, etc. etc. etc.
The Installers end of the business is not what it once was !
I am sure you will get some more input on this / the good the bad and the ugly of it.
