If you are strapped for cash and really just trying to generate eyeballs, head over to Canva and make an infograph. You can easily create a really visually appealing & informative piece around your niche.
From there I would submit it to all the infograph databases, I'd then tweet it out or privately tell other leaders in your industry. A lot of times they'll link out to just cool stuff!
Lastly, you could jump on technorati or something similar and compile a list of all the blogs in your nice. You could contact each and ask to guest blog or tell them about your infograph.
One day of hard concentrated effort would do the trick!
