Take the punt and venture out there or risk getting stuck in Instructing like some Pals of mine did.
Not that there is anything wrong with instructing, I really enjoyed it but you sound like it's time to move on. An instructor who is not happy or devoted is not doing his/her students or company any good. Just as important do it for your self.
As a back up, keep your Instructor rating current as there are a number of operators that do M/E charter as well as flight training.
