It's a great job, good luck with it! I wouldn't bother with the FAA nonsense personally. A company called Avtech2000 used to do a distance learning OPS course that was very good and recognised so you could look into that.
I've had two Bizjet OPS/Despatch jobs. The first paid me £21,500; the second paid me £17,500; and the company I work for now pays it's OPS staff over £30,000.
All the best.
