To find a job offer, you must find an employer. You can look for example at:
http://www.jobbank.gc.ca/http://www.monster.ca/http://www.eluta.ca/http://www.canadavisa.com/career_zone/canadian-immigration-job-search.htmIf you find a job, apply for it. Tell them that you either need an LMO for a work permit or an AEO so you can apply for the PR yourself. Employers are not all too happy about that but if they can't get anybody in Canada, they might be willing to go for it.
I would assume that an employer would rather that you come on a work permit than to help you apply for your PR right away. The reason is that if you come on a work permit, you can start working for them a lot sooner while if you apply for PR, it will take months, maybe over a year and they have no guarantee that you will ever actually come and work for them even if you get your PR because you are not obligated to and might decide on another job.
