plan on CFI'ing for a few years... or if you are in the right places you might try pipeline flying or flight watch...

with those few hours in this environment its going to be real tough. I will not discourage you from your dream but the reality of the business is such that be prepared for several years of LEAN.

Your ATP and FEx are only good for two years unless you are actively flying some sort of 121 or 135... ( correct me if i am wrong out there ) and I would say you probably wont have the quals to get your ATP in that time.... could but probably not.

I would work on your CFI. Worry about ATP and FEx writtens down the road.. and frankly there arent many places still requiring an FE written..... so I probably wouldnt even bother with that.

good luck....
