Went live with a small scale service business recently and am seriously looking into the branding kit platform. Soto answer your question I would pay for that one and the current price, while discounted, seems like great value.

I’m a fan of Pay once use forever models. Another site I purchased access to, with pdfs etc was “howacarworks.com” which has been valuable and was like $20

Good luck with things

Edit: not sure about the “become an affiliate” functionality though..
