Fairly new to this as well, but on the other side of the coin, LOL
I would suggest getting one, but, obviously fake handle like you have here, hobby phone and always blur out your face in pics. Don't completely blank out face as some do, which just seems like overkill and well, makes the pic look a bit weird to me.
If you have anything distinguishing like tattoos, get them blurred as well.
Tell people a little about yourself and your personality without going into to much detail of course, likes and dislikes.
A brief description of menu and prices of course.
As for who to host it for you, there seems to be a few popular ones out there but, i'll leave that to your research on pricing, but, you may want to find one where you can disable it when not working as you stated, wanting to keep things separate.
Just my 2 Cents, Good luck
