Show HN: Ideas to get more clients for freelancers and agencies

I've been working on a resource to help freelancers & agencies get more clients, thought it would be useful in these times.

Whilst browsing around I couldn't find a thorough resource with ideas and actionable tips, just blog posts. Whilst you may have heard a few of them before I think putting them into a handy resource helps you brainstorm new avenues for business.

Let me know what you guys think! Have you tried any of these? Any more you think I should add? Looking to continually update this.
