Angela, office support is very broad. If you document what you did in the office and your particular area of expertise you may have better luck for instance, answer telephone, typist, accounting, bookkeeping; that sort of thing.
It may be helpful if you take a look at the Department of Labor's
Dictionary of Occupational Titles so you can pinpoint all that comes under office support, sometimes we forget everything we do
just note what you actually did. See this title and what it entails:
office support, etc. you do not have to buy the CD rom offered just read the job specs for CLERK, GENERAL (clerical) alternate titles: office clerk, routine. Your site should tell people exactly what you can do for them point by point and why they should hire you. I used to use the DOT book and found it very helpful.
Also, I suggest that you visit the
Business Coach Site here.
