I like the idea. I’ve commissioned logos from one-revision-only designers a couple of times. Happy with the results both times and they were not what I would’ve asked for. I only used one revision on one of them, so close to zero-revision.
Organizations can be so stingy and precious commissioning logos; I encourage them to take flyers on services like this one even if it’s not going to be their primary design.
The chat idea is fun. The writing is good which is most important. The text size and gap between blocks were big enough to be legible to semi-quick scrollers.
