There are really no secrets or short-cuts. You just have to keep applying for jobs and hope you get lucky and find an employer willing to go through the LMIA process. Note that finding an employer and LMIA doesn't guarantee your work permit will be approved. CIC may stil refuse the work permit if they believe you use the study permit as a means of getting to Canada and finding a job. If at all possible, the better option is to stay in school and complete your program - or switch to a different program that is better suited to what you want to study. Good luck.
