I had a buddy of mine that is a controller at ZSE tell me that Raytheon, the company that does all the training for ATC's, is hiring people all over the country to be "ghost pilots" in their training program at ARTCC's and TRACON. They hire people who are waiting to go to OKC to give them a head start on the feel of being a controller. I guess the pay is pretty decent too (he told me $20/hr but don't hold me to it). If you go to rayjobs.com, register, and apply for "Remote Pilot Operator (Field)", you at least might have a chance of getting a head start on everything. Also, check to make sure that your city is hiring in the job description because I don't think all the the centers are hiring. Good luck!
