Don't take this the wrong way but you haven't flown for 4 years so your going to be behind the curve. In fact my local Aieral photography company would overlook you when looking for some one to fly their Cessna 150.
Add an SEP rating if you haven't already got one. Then complete an FI course over the winter and then try and get a job next spring/summer and start off part time (sat and sun) and have a proper job to help make ends meet.
There a fair bit of movment at the moment and I know quite a few instructors who have moved on over the last few months and none of them had more than a thousend hours.
