I worked for Aerosim before they bought it out, when it was DCA. A couple of things;
1. It's better to be a CFI in Florida than Texas. Weather wise... most schools in Fl will fly more days than TX.
2. Aerosim has a constant flux of international (Chinese) students, this is great for CFIs. Tons of students and none of them will become a CFI, means lots of steady work.
3. The area around there is kinda rough, stay away from the city and just drive to/from work.
4. Take the job seriously. You know in 5 years you'll start meeting people at the airlines who you treated well... or badly. Just remember that cause it's a small world and a serious job.
