Zondaracer has some good advice. I might through in buying a simple single engine fixed gear with about 1000 hours left of the engine. It is relatively inexpensive to fly and maintain. The days you are not instructing, hop in and build some hours, fly some triangle routes, volunteer to fly for the local sky diving club and ferry aircraft for fix based customers, etc... I did not get hired by a commercial airline till my mid thirties and still had a great career. Good luck!
