If you are really serious about this line of work, you need to go back to grad school. And don't get a master's in CS, get a master's in physics or something focusing on (applied) computational science. I don't really know of any companies who solely work on meshing; they work on the solving part as well. With a master's in physics, you could try to work at a company like COMSOL.
If you warm up to a professor and study with them for a while, they may give you a job as a TA or RA and you'll get free tuition (best case). Also, there are a lot of fellowships available for students interested in computational science.
Seriously, you have to play the education game. I'm 26 and I just got my BS last year. Why? Cause I was this smart when I was 17, but no one believed that until I had the degree.
