Many of the best web design jobs come from customer referrals. However, a great way to get started is by listing your services on websites like 99designs or Fiverr. Here, you can connect with thousands of potential customers who are searching for the exact services you offer. You may also have the opportunity to upsell them after they purchase your introductory offer.
Websites like Care.com connect parents with babysitters. The company does all the background checking and other due diligence to put parents' minds at ease. Of course, you can appeal directly to people in your personal network, but if you're looking to generate recurring revenue sign up with a site marketing to parents looking for child care services.
