Part 141 schools will hire you, they have huge influxes of foreign students right now. You might want to just start teaching student/private pilots at first to develop your technique. Going from zero experience to teaching someone multi-engine maneuvers is a scary thought. I sure wouldnt want to go up with you untill I knew you had some real world experience. No offense.
There is no shortage of instructor jobs, but there is a shortage of good instructors. Don't become a statistic by getting in over your head before you're ready. Do you really feel comfortable being PIC in a twin with only 250/70? If anything happens, its your butt on the line.
Fly safe.
