Actually I just moved into the neighborhood so I don't know much of what's around, but I did exploring of the busiest areas and only found this computer store - luckily 1 block away from home. I guess the amazement of them being that close, me not having a job (only 16 years old), and them posting a help wanted sign kinda got me overly excited about finding something to do.
I'll consider going in there again tomorrow or the day after and see if something can be worked out, but me being 16 (there is an unwritten belief from what I can tell in computer stores that if you are young or don't have one of the allmighty 'certifications', you are unqualified) doesn't help things - having neither the experience of negotiating for a job, and difficulty speaking to strangers doesn't help.
As for self-employment, I'd love to but don't know how. This is a large city and it's hard to compete - especially when a store with reasonable prices (1 ghz PIII system for about $700) is nearby.
