I agree with pretty much everything they said. The best thing you can do is come prepared. If you bring a laptop. have a copy of the adventure you are going to run and a paper copy. Bring First Steps with you and a just in case scenairo you like to run. If you are hosting keep in contact with the DMs. *Especially the day before the game* Just a quick whats up helps alot. Get feed back and dont be afraid to ask.
Wear a Pathfinder Society Shirt or Gaming Shirt. I know The VL said this already, but: Advertising! That is a big one. Word of mouth within our gaming community helps. See what the rules are about reserving a table or tables. Know what you are walking into. Not just the size of the store, but the area. Do a dry run. Scout it out and talk to the stores. They love you because you advertise for them. big groups mean money. People love to see a busy place over a dead place. My friend Runs a World of Darkness game out of a Coffee Shop in the Back room. On other nights you can find him running his Pathfinder Home Game out of there. Nothing like Jacked up RPGers running around on pure caffine. Kind of like that scene from scanners :)
Fliers all over. I post on meetup, In the store if they allow it(I havent been to one that doesnt), On the stores online event calender, Comic book shops and their boards(ask first or if you are chummy with them they probably would not mind. Most Comic shops like to support gaming because they tend to be gamers themselves. Wonder Twin Powers activate) and dont forget to post on the paizo boards AND the event Calender. You may pick a player or two off the boards and/or the Event Calender, but the vast majority is going to come from the fliers and posting at the store you plan to run at.
The last thing I would say outside of minis and books is: DMs. If they are Dming then they have the pulse. They probably have a home group or know others. If you are new to the area. Talk to your DMs. They maybe able to hook you up better than any store owner or the other VCs. They have done the ground work for you. You never know til, you ask. They can help you. Not just the DMs who run for the event, but the guy who runs with the same group every sunday for the last 5 years at the same table that is THEIR table. That guy. He can help. You never know. HE maybe dying to be on the other side of the screen for a change. Good luck!!
