Would you use (and pay for) a waitlist form creation service?

While building a waitlist form for one of my products, I realized that others might be spending the same few hours I did creating something similar. So I’m considering building a service that helps users quickly create custom, embeddable waitlist forms — for products, events, services, or anything else.

I can share more details about how it would work, and I’m ready to start building and deploy as early as the first week of November. But before I dive in, I’d like to know: is this something you would actually use (and possibly pay for)?
