Have you actively contacted companies you're interested in and asked for interviews? It's much harder to wait for someone to contact you than it is to send a personalized e-mail / resume to each company you're interested in.

I'm also a tad worried that you skipped the portion of my post regarding looking for pure graphic designers. It may just be my experience from companies I've been in but the last two graphic designers I helped hire were combo packages.

It's nice to see another 19 year old excited about startups and technology though :)
