Hi there techs. i live in the US. Do you think it's possible to average $400-$500 a week repairing computers on site. I mean at people's location ??

I heard tablets are slowly replacing desktops on consumers preference. I'm pretty good with computers, and i know it's gonna take time to build a customer base. How many jobs a week you do ?? can you make a living out of it ??

I'm not looking to get rich with this, i'm single, no kids, don't need a lot of money.

Any input will be appreciated.
