Mobile Diagnostics- part time

Hi, My name is Moses Brown living in Monroe NY I have bin in this field of auto repair for the past 20 years and also a graduate of Lincoln Tech Institute Mahwah NJ in 2004 as well certified with ASE L1 advanced engine performance,I was thinking for a long time now to do this diagnostics as a part time job or a hobby , me seeing this clear training from Dannner i got encouraged to my dream ,but i have a few questions in this regards 1) will this training in the premium section suffice for all newer car models 2020 and newer? 2) will this training be good for hybrid or electric cars as well or should i seek special training for that? 3) as i plan to relocate to Casa Grande AZ 30 miles south of Phoenix Soon, is their a training that you know of that will be a help for me ? Will appreciate your response.
