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.
Next, you’ll want to pick a WordPress theme from somewhere like ThemeForest, Elegant Themes or OptimizePress. This is the barebones design of your site, which you can then customize with your own branding, copy, and images. That being said, you don’t want to cheap out. It costs less than $100 to buy a theme that will make your website look professional (and you can upgrade to a completely custom design once you get the business going).
