Do not do custom installations unless you have the legit certifications and a legit registered business otherwise scuzzy people for a ride and they end up getting there system installed for free. If you dont have a legit certifications you cant charge what a business that has certified employees charge. I own a custom car shop and do not do stereo installs because I am not certified to install stereos. Yes I know all about electronics from schooling. Basically you not having certifications your looking to get sued by people and then it can come on you with taxes because not claiming income and sales tax. So before you do this just get a certification and license your business. Do not do work for people you do not know until you have a licensed business.
