Hello simpleperson,
I would urge you to do the following:
1- Check the 29 NOC list and identify one or more category that
might match your job duties
2- go to HRSDC
http://www.hrsdc.gc.ca/eng/home.shtml and search the job code
3- Go thru the duties at HRSDC with what exactly you do. Don't bother much about the job title, focus on the duties instead.
If you manage to find similarities, then you'd be lucky, you check the cap then and make your mind.
Hope this helps.
Cheers!
