Fortunately, automated penetration testing tools like Acunetix web vulnerability scanner allow organizations to scan anywhere from a handful to thousands of web applications quickly, cost-effectively and, most importantly, continuously. Pen Testers are able to leverage the pros of automation for their web penetration testing freeing up their time for more important manual tests.
OpenVAS is a very capable community supported vulnerability scanner. Your plan to assess as much on your is wise. You absolutely don't want to waste money paying someone to find things you could have easily found yourself. You want to spend it on someone who can find the things you could not find.
Snort is an IDS, not a vulnerability scanner. All of these typically rely on use of CVE's provided as TLP White by US-CERT. Other TLP levels require an ISAC and or membership due to sensitivity. Also, I would suggest you validate these as well (because some will be detected that are false). If I may ask, is there are reason you are seeking open source utilities?
