The trend right now is definitely one page portfolios. Most clients actually prefer that.
I'd suggest coming up with an alias to display your work under (for instance mine is "infektsu" which means "Infects You" - meaning behind that is I hope that my work sticks with people, aka infects them). Register a domain, make a simple yet nice looking single CSS page and throw your work on it with short descriptions.
Actually here are some links that you should find helpful...
