Where Indeed excels at finding job postings across the web and acting as a search crawler for employment, maybe a full-fledged career is too big of a commitment at this point in your life. Elance is a site to find freelance work of all types. I’ve used it for quick writing, editing, copywriting, resume building, and other odd jobs and temp gigs. The experience has been great.
Research other listings in your city on AirBnB and see what the going rate is for a place like yours. You could also just rent out a private room as well or even a bed in a shared room. In fact, that's how AirBnB got its start. However, you might find it hard in the beginning without reviews, but as long as you take really good care of your guests and provide a lot of value, the reviews will eventually come rolling in.
Monetize a hobby. While some hobbies actually cost money, others can be transformed into a profitable business venture. Ultimately, it depends on what your hobby is and how talented you are. You could turn your love of photography, for example, into a part-time gig taking family portraits and wedding photos or selling prints on Etsy or at arts fairs.
