Lester's bodyguard, Benjamin, is quite reliable. Although they are a legitimate security company, who doesn't have a few friends?
Knight Club is a very interesting establishment. On the surface, it's just a regular membership club, but in reality, it's a recruitment spot jointly controlled by several well-known PMCs in the industry. For some retired veterans who have the channels to know about it, it's also a place to make money.
The security company where Benjamin works has nothing to do with here, as they mainly provide bodyguards for critical missions, whereas PMCs usually collaborate with international organizations, NGOs, multinational institutions, and the military. Most of their work involves foreign affairs. Through someone's introduction, he learned about this place and once came seeking work, but ultimately declined as PMC work is mostly overseas.
