I'm sending you positive vibes....keep going. Don't give up! I've found that networking is the best in landing a job. Again....LOOK UP your Rolodex and arrange a quick lunch or coffee time with your old colleagues. That's how I've landed my jobs...through connections with my colleagues and peers in the field.
Emails, sending out resumes aren't cutting you because there's no face-to-face contact.
One final thing is to sign up for a Meet-Up group in your area with the specialization you're looking for. Some have business contacts and start-ups.
I would like to see that you've signed up for at least 3 Meet-Up groups by Wednesday...'k?
