Zulu; Aqua and the other player's concern is this. And is is a valid one.
You are a person who's new on the scene and that no one has really heard of.
You're here now touting an event that's new, more expensive than other established events (a lot more expensive) at an unknown location supported by a group not known to the community.
Many people have come before you making the same elaborate claims, a huge event or other promise who have promptly shit the bed and become persona non grata.
What I'd suggest is first meeting with the local player base to get yourself out there. Then getting age verified so you can chat in the adult section of the site and last putting on a few taster events at the location to create a buzz and sense of legitimacy around it
As I was typing it looks like Aqua has said the same, a bit more plainly.
Airsoft, where nothing is hurt but feelings.
