I wouldn't start up a mail order company. There are already way too many places that sell parts, and I think you'd be hard pressed to fit into the marketplace without offering prices that are way low, and I don't think you could build the volume.
To start off, I'd start looking into other possible jobs that you can use your skills, and you're not always going to be able to use all your strengths/do what you love. Times are kinda tough now...I'd just look for a computer job that pays nicely, then when the job market opens up or you earn more experience, then think more about your own business of some sort
