Information about the Express Entry program and how to apply can be found here: http://www.cic.gc.ca/english/express-entry/index.asp
If you do not wish to read through the application details on your own - then I would recommend you hire an immigration lawyer to assist you.
Whether you will be selected or not depends on the number of points you have under Express Entry. If you have 450 points or more - the chances of being selected are good.
