For $4-5, learn to write, do backlinking, microwork jobs, et al, and do enough of it freelance to earn that much a day consistently. Put in a twist involving manual work others can't do or haven't figured out, to stand out.
As in, be a digital problem solver--- if somebody wants blog or forum comments from quality sites that don't allow spammy commercial links, find a way to link to urls that are not spammy (say, link the comments to guest posts or press releases that contain the money link). May take more work to set up, but you'll become known to be the one guy who does it. Rinse and repeat with other 'problems" needing elbow grease to solve.
