First of all you will need to find a job and then ask the employer if they are willing to support your PR application thru AIPP or not. Because they will have to do lot of paperwork and disclose some business documents to the government. Small business might not want to do it.
Second, if they are willing to do it then the employer will need to apply to be a designated employer. There are forms and required documents that have to be filled by employer and submit it to the provincial gov't. If approved, the next step is filling endorsement application forms and get a settlement assesment from immigration officer. The immigration will refer you to go to a place where an officer will assess what you need to settle down in the province, for example need a living place, or english course, etc. Its for free. The result of the assessment will need to be submitted along with the endorsement application forms. If approved by provincial govt, the provincial govt will give you endorsement letter.
This letter has to be submitted along with your PR application to the Federal. After you got endorsement letter, you are on your own. I meant, you dont need your employer to do paperwork for you anymore. This part is employee's part.
Hope it helps,
