Social media or copywriting. Anything to get my feet wet at this moment. I'd love to work in the football industry liaising with fans ultimately :-)
LinkedIn has been where most of my work comes from -- people just find me there, based on my profile, and say, 'you available for xyz?'. No hustle involved.
I recently found Upwork, which lets you bid on projects. The rates seem to be a bit higher than on other, similar sites (eLance and ODesk in particular are garbage), although for my situation, the projects are below my (medical writing/medical copywriting) expertise level and aren't in the ballpark of my rates. But if you're just looking to get some extra portfolio items that you can use to strengthen your LinkedIn or personal website, that seems like a good place to get some small one-off projects alongside the work offers you already have.
