Charon would probably be one of the founding/early members. As marcoasalazarm said, there is one prerequisite for hiring us, and that it that the target has to deserve it. Charon's regret and semi-guilt over his history as a hitman would likely lead him to form/join a group of vigilante-for-hire types. If he were a founder, he would be way out of the spotlight when it came to actual leadership.
Also, my inventory got messed up while I was redoing it for organization, I will hopefully have it repaired by thursday at the latest. For now, I have put the basics down.
