Formally Employeed selling electronic components and cabling.
Do sideline installs for friends and slowly starting to do it for contract. I started when I saw the need for a reliable installer due to the quality of work that my departments were recieving. I do not have a set shop, I do all of my installs mobile to where the customers are. I carry a fully stocked truck with wiring and connectors and everything but the actually compnents all the time.
I've been in the install business in some form for about 6 years and selling electronic compnents and accessories for 4.5 years.
