As best buy doesn't always have great install bays, I would like to suggest the grocery store.
Not the greatest pay or hours, but it is indoors, cool temps (usually) and u meet some decent people working there.
other thing is look to places that do shipping. ?In doors, just box, label, get the $$ and ship. Like the UPS store.
On the off hand topic, I give you props. you have the balls to admit ur mistake, and you are learning from it. Above all that tho, the fact that you are driving on is inspiring. Next time I am bitching about shit this is gonna stick in my head.
If you need some other ideas, let us know what ur good at man.
