Ask HN: Do startups hire Non-Tech Telecommuters?

Being in a location of the US that isn't anywhere near a hub for technological innovation, the job and internship market for startups in this region (southern FLA) is virtually non-existent, I need some advice.

I do understand the concept that business, marketing, sales, social media, and govt. relations positions are either rare(not needed) or are filled quickly. Being a non-technical entrepreneur with a desire to join a startup (even in an unpaid intern capacity), where should one look for such positions? It seems as if they don't exist? Would it be unprofessional to email a few startups offering my cover letter and resume for consideration?

Any insight would be greatly appreciated!
