I believe this is the same guy/company I did a search for back in mid-2007.  I couldn't reach him on his GA# when his invoice became past due.  I always left voice mails.  From what I can recall, after much hunting, I found his email on a notary website - don't remember which one.  He finally did call me and said "sorry...he had been out of the country".  I did get paid finally and never heard from him again.  I have an email address I believe is his that I found in my sent mail.  If you want it, please email me and I'll give it to you.  I don't want to post it here as I am not 100% sure it is his but I am 98% sure!  His initials may be MDN.
