Why not double-down on word of mouth?

Leverage your previous clients' social media and professional networks instead.

Brainstorm things you could do that would increase how often they recommend you on their social media or privately.

Some examples from the top of my head:

• create content marketing assets that your previous clients would want to share on their social media. (e.g. interview them for a case study)
• start a newsletter with industry insights, best practices, etc.
  
• referral program
• coupon code that your previous clients can share
