I've had 4 in my life:
It depends on exactly what you want out of it. If you just want to be adored and have an allowance and your bills paid (you'd better be a really hot twink or a really hot gym bro), you can find an arrangement like that (daddies like that usually have ED or some other disability that makes sex difficult or impossible), but that's NOT easy to find.
In my case, I wanted good sex as bad as I wanted the financial arrangements and I was already in a social atmosphere where I could meet older openly or closeted gay men, so my first arrangement was offered to me without me asking or even thinking about it. That one lasted for about a year and after that fizzled out, I almost immediately got in one with his best friend, which was the easiest one bc he was married and had a family, so sometimes it'd be a week or more between us seeing each other, but he still gave me everything he promised.
Another was the District Manager of a company I used to work for who made me quit so that we wouldn't get in trouble and paid me my full wages for like 6 months until he moved to the East Coast.
My last one was a Seeking Arrangement match from 4 years ago who I could probably call and get back into an arrangement with, but honestly he could have me for free bc he's a SUPER hot construction company CEO and the best combination of a HUGE and PRETTY cock I've ever seen
