If you are a freelancer, you can sell your services, through your website or blog, your social pages, webmaster forums, as well as freelancing sites. To get more clients through your site, you need to receive a lot of traffic, with social sites, you need huge followers, on freelance websites, like Upwork or Fiverr, you need lots of good ratings and reviews. If you're new or don't have many ratings yet, it's hard to get clients to pick you.
