What is a reputable company to hire for Linux Server security?

[Kido1986]

I have a client (we manage their office network and email) ask about where to hire a security expert for their 100+ domains, all on Linux servers. They are getting hacked repeatedly. I cant risk asking random people off of Craigslist or something, I need a reputable company.

Any suggestions?
