Heads Up Tournament Blinds Structure Question

[TFGoose]

Hi all,

I'm hosting a HU single elimination tournament at my house in about a month, and am trying to figure out an appropriate blinds schedule. Our regular NL MTTs begin with 3000 chips and a 25/50 level. I'd like to start this tournament somewhere in that neighborhood, but I don't know how to escalate the blinds as each full round concludes.

I'd like each individual match to last somewhere in the neighborhood of 60 to 90 minutes, and I expect around 20 to 30 players. Does anyone have a suggestion on how I could structure the blinds to accomplish this, or have a link I could consult?

Thanks,
