Information Security/Penetration testing companies?

I would love to get some sort of experience like this in my area, but there are no companies like this around here, within two hours at least. Which brings me to a question. Do most companies even perform regular security audits? If so, who performs them if there is no local company which specializes in the field?

Now that I mention CEH... If you, like me, got enthusiastic by reading their brochure about job opportunities for a CEH, I think we'll both get dissapointed
I think it's something most companies just don't consider, but most likely should. Of course, if you have the necessary skill level to perform or participate in an audit, then perhaps if you approach them with the proposition, maybe they would listen.
True. I think most companies, besides the Gov. don't really deal with network intrusion until an actual pentration occurs. Then they have an in house guy fix it. Because according to the rest of the company, IT can fix anything.
I think, apart from certs like the CEH, firewall and IDS certs (Cisco IDS, Cisco Pix, CCSA/E) may be a good step towards a penetration testing/sec auditing job.
