>>19845797Philly is over saturated with schools and promotions. So that might be a little tough.
For areas you want a building that can fit an 18x18 ring with adequate clearance on at least two of the side. You also want tall ceilings so wrestlers can use the top rope. Running out of a building that can host shows would save traveling and labor costs, but now you need a spot that can hold a few hundred people and has good parking.
Most schools don't run open shows because they lack the space. They will do small shows for friends and family of the students, and then record them and put it on YouTube. Promotions that run larger shows, 200+ people, usually rent a ring and have an arrangement with a venue, usually booking out multiple dates months in advance.
If you're trying to break in, go to shows and talk to the promoters. Sponsoring shows could also be good, as you will get a better idea of what you need to do logistically to make the shows happen.
Marketing is difficult because indie wrestling is in the shits right now. WWE ran off so many fans over the past decades, then then and AEW snatched up most of the wrestlers worth watching. MLW does okay, GCW does okay on big shows, and CZW only draws like 50 people outside of their death match shows. Most other indies around Philly are attended by the same 30 or so ex-Chikara fans and friends/family of the wrestlers.
I think to be successful you need to have great in-ring action, good looking wrestlers, and solid production so people can easily find footage online and actually watch the matches. I think there is a spot for a new promotion, but I'm not sure what the unique selling point would be that would capture the audience. I think you would have to appeal to the zoomer/twitch crowd and get then hooked. They already spend hours a day watching people play video games or talk at their computer. So doing something similar but with wrestling may draw well.
