Finding and living my passion

Hello Everyone,

My name's Matt, i live in LA, California, i am currently working at a Car Modification workshop and i have a true love for cars and just the modification of it is what i live for but for the past few days i realized that there was no growth in working at a workshop and not being able to design & modify as per my interests and also these days, youtube has been going crazy as majority of people have started their channels, i am looking for a way by which i could set up my own workshop but make it available digitally, i.e you can design your own Mods online and we'll be performing it in actual, you can get the design you want from your home itself but the problem comes in regards to the investment required plus i won't have a job if i start this and it would turn out to be difficult to manage everything, is there any way i can achieve this?
