I don't really know if your story is real but I have doubts reading some of your posts!!
I you have 500 hrs on a 737 I see no reason why you would not be of interest to an Airline.I don't know where you live or if you are prepared to move to secure a job I am i the UK myself.
Straight off if you have those hours you could apply NOW to both Easyjet and Jet 2 there are probably more also.
If you are genuine you should be active everyday and a damn site more positive than you come across as many would kill to have those hours on their c.v. including me!
Just check everyday on here on ppjn.com and on latestpilotjobs.com that would be a start.
By the way if you have made your story up your pretty sick my friend and I suggest you go get some counselling!
To say that the 737 is not complicated by the way is
! I recon you could fly it for 20 years and still be learning new things about the aircraft....
