Looking for a single ticket to Monday Sept. 18th game

Looking for a single ticket to Monday Sept. 18th game. I will be in town for work and have not been to game in a few years(Heinz field!) I will take anywhere inside as I can get a single 500 level for $100 on resale sites. I may just go and look for tickets while tailgating but that can be annoying and prefer to have ticket secured ahead of time. Happy to meet pre game, share a beer, trade a story and VENMO or pay cash for ticket. Thanks!
Here we go Steelers!!!!
