It's an interesting idea. We've been toying with this too in our UK app prototyping and development company. Many of our startup clients receive those services as part of a bespoke package, so productising it could increase our appeal by simplifying the buying journey and making successful outcomes appear more predictable.
Our sales guy is worried that the variable scope / fixed cost is dangerous, but I do think we could limit the scope in that there are finite activities.
Would be interesting to hear if it works out.
pretty bizarre that your primary CTA directs people to a self-aggrandizing medium article.
Also, your 'low five figures minimum' starkly contrasts with your canned packages that run as low as $1,000.
