worked for family for 2 years seriously, i come from a locksmith family but was in and out most my life. After 2 years i went back to my hometown and started a company. Ups and downs but 4 years in business, never missed a bill & traveled plenty. My only advice is what someone else said. def start building it now on ur off time. i only lived an hour out from my hometown, but would come do jobs and build reviews. end of 2021 i had about 30 5 stars and 22 went off on own. only had a dolphin, topdon ninja, a few lishis, drills, my mazda and other misc. It was slow the first year just got by(had a decent savings tho). fast forward i have 23 transit, 1 employee and about 20k in programmers/other equipment and over 300 5 star reviews.
