Service providers, how did you reach your first clients?

I'm at the point of the first client! Yupi ya yeah!

Our business model and investment require quick growth.

Any tips on how to get first clients? They are dozens of long term ways which we're developing but that would take time. Creating content, improving SEO, building credibility via Linkedin.

Anything you did in Pareto 20/80 way?

Any words, much appreciated :)
