Requesting tournament

I have a Instagram page @chess_is_amazing I want to conduct a tournament for followers , how do I do that ?
I want to name it particularly according to my wish
And on a particular date

@rcostheta i want tournament with specific name and day

You can call it "XYZ (whatever you want)" arena. And just announce the tourney but you have to create on the day of the tournament (up to an hour in advance). Not much more you can do that I know of.
