I'd sit tight where you are now as it seems you have your foot through the door. They must think pretty highly of you to pay for your type with such low hours. The last thing you want to do is burn that bridge trying to relocate for quicker hours (that may or may not pan out). If you don't have your CFI's yet. Get them, and build time the old fashioned way while keeping your foot in the door with your benefactor.
just my tarnished pennies.
