well, which NOC is appropriate for you? check current occupation list:
http://www.cic.gc.ca/english/immigrate/skilled/complete-applications.asp
it's true that you can't include your mom while filing your application, but after getting your VISA, you can apply for "Super Visa" for you mom. Please note, Super Visa is "visit visa" not immigrant visa, however, it's validity is 10 years
.
if you want to know more about super visa then visit following page:

hope this helps
