Hey everyone, newbie here!  Been reading a lot on here the past few weeks, so thank you to everyone that contributes on this site.
Here's my current situation.  
Clearance:  TS/SCI
Current Employer:  Army, 4 years, leaving in October.  Combat Arms job, so no IT work there.
Experience:  I have little professional IT experience, worked at an online hosting company doing tech support (but mainly sales) for about a year prior to joining the Army.
Certifications:  Studying for Security plus, plan to test mid September.
Desired Job Location:  Middle East, just started reading on here about Africa (intrigued, but not too sure)
So here are my questions:
With having little experience will it be hard for me to get picked up for a job? 
What jobs should I apply to?  Help Desk, or something a little higher because of my clearance? 
Who should I start with ?  I see a lot of people go with Vectrus on here, but since I already have a clearance should I look elsewhere ? 
Is there a pay difference between Secret vs TS/SCI clearance?
What's a realistic salary expectation?  
How long does the process usually take from application turn in until you're on country ?  I would like to leave begining of the new year.
Does OCONUS contracting look good to CONUS employers ?  I plan on doing 1-2 years then coming back to the US and working for Boeing, General Dynamics, Northrop Grumman or other Defense Contracting companies in the Phoenix area.
I'm married with a newborn.  The primary reason for me wanting to go OCONUS is for the money and experience.  With the already saved money and contracting money I'd like to have a nice down payment on a house.   The wife is ok (but not excited) for me to go back overseas if the money is right.
