I want to help start an organization (not sure which kind it would be) that can be used to continue the Trump populist movement and expand it.

I thought this would be a good place to find people to help with this.

My main goals are to promote true conservative values and spreading truth among the people in a grassroots manner.

Ideally, I would also like enough people to help find candidates, particularly America First and outsider candidates. It doesn't matter how they label themselves (Republican or Democrat), in fact the appearance of a non-partisan organization is even better in my eyes. For example, my area only puts Democrats in office so I'm registered Dem for when I want to make a run at office.

Promoting truth over media lies, finding candidates, collecting individual donations, and providing advertising services would be the goal.

How can I (and others if interested) go about starting this and what legal designation would an organization like this fall under? Like a PAC or 501(c)3 or something of the like?
