This looks more like a marketing stunt in itself (it's only 5 pages of well-designed copy) than an open source playbook.
I wanted to share how we get on, what works and what doesn't with everyone. We've been growing the business through LinkedIn / Call outreach so far, and it's probably why despite being a successful business, in my opinion we're underachieving on the potential.
I recently had a choice to either outsource marketing or hire, and I chose to hire but junior. Part of the reason I started the business was to challenge myself and I'm really enjoying exploring marketing.
On another note, I'm very happy that you said it's well-designed! I made it in Canva :).
