Publish your add. It is that simple.
Or, if you want to be proactive, look at the ads of people requesting graphic designers and contact them.
Craiglist is just like a huge list of ads so it is a matter of search and be found 
Yes, all you need to do is publish your add. But, I must warn you to beware of Craigs List. Because most of your business will be over the internet it will not be as dangerous but, there have been many sketchy interactions on Craig’s List. Just be cautious in how you receive your payment. Not everyone is who they claim to be.

There are plenty of ways of monetize a site. It could be through affiliate programs or selling your own products such a book with the most inspiring images or by getting premium content for subscribers, advertising… plenty of ways, really
