Not sure how much lab expereince you've got, but why not work in a lab? that's what i do. For me, it's just to get some experience in a job and party and travel a bit until i figure out what i want to do permanently, but for someone with your list of wants, it might be an nice fit.
The upsides of the job aren't too bad. I work in a lab with people who are deeply committed to their work (PhD students, post docs), there are lively discussions every day, and there is the opportunity to become a specialist technician in one area if you so choose. Once you get a few years of expereince, you can make upwards of 50-70k (as a lab manager or speicialist technician). It also gives you a head start on research techniques if you ever want to pursue a PhD or some type of research project in med school, etc. I also come in and leave whenever i want (within reason) and usually have no problems scheduling a vacation whenever i want.
The downsides are that you work alone a lot, and that it can become frustrating and monotonous at times. You'll also be resricted to living in cities with large universities, bio/pharma comanies, or reserach institutes.
Let me know if you'd like any more info, tips, etc.
