curious about procedures

I am going to start repairing hardware on lap tops, Tablets, smart phones, Digitize-rs, Leds,Battery replacement. What Insurance and bonding do I need?

Course there is tons of info on the net... Here's a simple overview:

I quit working on other peoples stuff... When you talk to a person about formatting their drive and ask them if there's important stuff.... They don't understand formatting... And the thought of wiping out someones Novel they've been writing for the past ten years is mind blowing...

If you use your car in the course of this business it'll probably need to be put in a commercial status with higher costs...

Thanks for the input Steve.
