How can I scan my companies external facing IP for vulnerabilities, such as malicious attacks, attempts at gaining access to our network, and any other bad things like that? I know about the QualysGuard service but I'm on a tight budget. Thanks.

You could start with Shields up.  An internet based test of your external fingerprint.

if you have a machine on another internet connection you could run nessus ( http://www.nessus.org/nessus/ ) on it to scan you network

"for vulnerabilities"
You may subscribe to any pay-per-scan service (which doesn't require buying any hardware) like Qualys, eEye Retina, Mcafee..etc
Or you may do it yourself using either commercial tools like Nessus and the above mentioned ones or free ones like openvas (which is based originally on Nessus).

"malicious attacks, attempts at gaining access to our network"
These types of things can be detected by enabling logging of your firewall and/or having an IPS. You can then analyze these logs to look for suspicious activities.
