If you want a job someday with more than one engine, go for that now. If you want to fly as you do it, try a single engine job as you work on your multi. My first job was flying traffic watch in a C172 6 hours a day. There is banner towing, pipeline flying, skydivers, cargo, corporate, etc. I had corporate jobs flying a BE-A36, C-182, PA-? (turbo saratoga). Eventually I got a multi and multi job flying a Cheyenne II and IV. There is lots of single flying out there to do. Of course there is the CFI thing, I did that for 1600 hours too.
