Is there any use for this business idea?

I’ve been thinking for awhile about starting a side business related to this sub. I love making itineraries, helping people with reservations, and generally playing tour guide, especially with travel around the city. I do it for friends and family but also for mutual friends and acquaintances.

Basically I would charge small fees for all these things, with a tiered system that charges more for more hands-on service.

Do you all have thoughts about this? Also, I’m wondering about the policies or ethics about reaching out to Redditors when they post in subs like this. I don’t want to be a spammer.

Thanks yall.
