Chances of employment with your experience-little to none.
You are too far away of the magic "1500" hours most insurance companies require, and you do not have a type rating on any MPH to act as Copilot.....
Best chances would be to get a Copilot position somewhere, and gain experience..
You can not be employed as PIC with those hours..especially, as you do not have a work permit-and even more because a company supporting you to get one would need to show proof that there is no local pilot available with the same or more experience...
