You can make people contact you for jobs. The best strategy when it comes to really make money in Fiverr is to post jobs for $5 but create upsells with it. In short, do more tasks that charge far more than 5$. For example, someone is looking for a logo designer for their site. However, maybe that person also needs a website. So you could charge 1000 USD for a full-scale website. Make it a lead generation tool for your business.
