Are you a designer or a web designer aka a builder of websites?
If you are the first, you would create designs or collect them on a page to showcase your asthetics. Lookup fiver gigs and their portfolio and put yourself in the shoes of a buyer. Would I buy from this person? Can I see what they like to do, what their style is?
If the second, you just need a list of projects - there should be enough organizations out there which would be happy with a new built webiste.
Then take on a few projects in areas you like working it.
