UK I run zedfull autel 508, fvdi, xtool, obd helper, tango, orange5 and of course your cutting machine a vast amount of Lishi picks, blades, remotes etc and everything is changing so more eeprom work is occurring.
All in all if you think you can do it then go for it it but be prepared for a rough year or so of business. You will also be competing with people who have done it longer and got experience. There are more factors also do you have a mortgage and how will it be paid etc also you need to research your area to see whom is working it etc
