Many of you may know I have started doing various freelance work for graphic design...I have now "mastered" (take note of the quote marks

) xhtml and css.
I want to bulk out my portfolio as quickly as possible...how would I go about doing this? I'm not keen on offering work for free as I know it doesnt do the industry of design any good so should I be offering my services at a reduced rate or will this not help either?
any ideas really appreciated.
Oh, and before anyone says "There's no such thing as a Get-Rich-Quick scheme" . . . its not necessarily what Im looking for
