I think alot of people are directed through the site via compUSA....like if they buy a router or something.
I've gotten multiple requests, but only dealt with one client.....a few times.....so i got maybe $125 from just a few trips. It depends on your area though. Wilik I think was making $60-$100 a day on just installing routers and simple stuff like that.
It helps to have a cell phone with SMS so you can respond faster to requests.
