I remember what it was like to be at that stage as a CFI. The first 100 hours of being a CFI is great and then when the 101th hour hits and it is kind of downhill from there on. I'm talking about working over 70 hours a month when you are a CFI.
A first officer job will be more exciting than what you are doing now, but the problem with taking a first officer job now is you will end up making a lot of sacrifices for less pay and less flight hours.
My advice is to give Alaska a try in May. Get a ticket to Anchorage, rent a car for 3 days and go around to the schools/ freight operators and tell them you are an 800 hour pilot who has always dreamed of flying in Alaska.
I think you will get the greatest quality of flying, the most flight hours, and the highest pay in Alaska. Even if it is just 3-4 months you get up there, when you come back to Georgia you will feel recharged.
