I appreciate your point that some products are really not SaaS-oriented, yet try to be.

But your two examples here seem exactly the kind of long-term customer relationships that benefits from SaaS. And may in fact be underutilized. These are high-touch, deep background kind of gigs, rather than impersonal service sites. I want to have an ongoing conversation about my task and I'm willing to pay a retainer++ for that privilege.

You make some great points, but I question a design firm that allows for 'unlimited' number of requests/revisions/brands.
