If you look for Billing Co-ordinator on the NOC, you will find
http://www5.hrsdc.gc.ca/NOC/English/NOC/2006/ProfileQuickSearch.aspx?val=1&val1=1212&val65=billing+co-ordinator which is a NOC 1212 which is a B-skilled job.
With FSW, you would have to have a job offer to apply since 1212 is not on the list of 38 most wanted occupations, see here:
http://www.cic.gc.ca/english/immigrate/skilled/apply-who-instructions.asp#listIf your job duties are similar enough so that your job could classify as a 0111 financial manager or 1111 financial auditor or accountant, you could apply under FSW without a job offer
You will not get double points for having 2 relatives in Canada but one thing you could look at is if your relative in AB can sponsor you under AB family support, check out
