As far as corporate opprtunities, I'm fairly deep in the business and don't have good news:
No ATP
No corporate experience
No recent experience
1 and 3 knocks you out of the majors and all three will knock you out of corporates. It's a tough market as stated above.
You need to fix the ATP and recent experience with jet time, not CFI time. Networking is NOT handing out resumes; you need to get a known and good reputation; be known by hiring officials (those who can make hiring decisions) and to make your networking help be seen as valuable. Valuable means do favors, be seen as reliable, offer something of value by those that can hire you.
