Ask HN: Moving from Education to Startup?

A friend suggested I post here for help after lurking here for awhile.

I'm losing my job as a high school English teacher and am interested in going into the startup world, particularly because I think it's where I can truly be useful and my work habits would be appreciated more. I have no idea where to start though with rebuilding my résumé; I've only been teaching for two years, but teaching and coaching is about the only experience I have beyond the sales positions I had in college years ago.

I was hoping to get some advice about how to reformat my résumé to appeal to startup positions. I'm very limited in CS (some Unix and Ruby/Rails) and would be more useful in a marketing or management position, or so I think. Would appreciate any help. Thanks, HN!
