You built something that works. The question is who runs it next, and whether they will look after it. That is a question about a person, not a process.
Nothing is public. You see who is interested and what they would do with your business before anyone sees your numbers.
You talk to the person taking it over directly, from the first message. Fit first: the trade, the town, how hands-on they plan to be.
Some owners walk away in a month. Some stay a year to see the handover through. Both are normal here.
Three questions, no account, nothing shared with anyone. You get a range and a plain explanation of what moves it.
