To qualify for a job with LMIA, you need to have skill/experience/education that employer cannot find ANY Canadian to take that job.
Looking at what your post, your skill set doesn't look unique or in demand.
Employer going through the application of LMIA needs to pay $1000 to apply and wait for the approval process to get the employee. So it needs to be special and worth their money and effort. If they can just hire anyone in Canada to do that job, they won't hire someone from outside.
