Congrats on your first launch! I launched a service like this in 2014 on HN as well :)
I'd really encourage you to focus on quality vs quantity here. I see you have 366 sites in your google sheet. Having spent A LOT of time going through those sites in the past, I am certain that 70% of those listed are either low quality, inactive, or irrelevant. I found the best success for customers when I spent most of my time sourcing/curating the list of only the most relevant and actively maintained sites. That's where you can deliver value.
I lived at Auroville for 3 months for a college study aborad. Wild experience. The Matramandir (the big gold dome) was a very remarkable and weird building. Definitely cult-ish, but also so truly different and innovative.
What would really sell me is if there was some hardcore copywriter/marketer behind it as well... that coupled with your great design skills would sell me!
