Alternatively/additionally maybe you could pitch niche projects you think you would be great at because of past experience (update code to new versions/libs, add a contact form to existing homepages, move things to cheaper hosting, integrate an internal system with someone's existing crm, automate marketing emails based on customer activity, etc).
Outsourcing is risky - help derisk it for potential customers by making them feel like you can deliver, you're trustworthy, you're competent, and you understand their needs.
I believe in you and I hope you get so much contract work you never have to get another fulltime job.
