I had a miserable time getting paid by them last year.  I was getting cheery emails from Andrew telling me that the check was in the mail, but when I contacted the bookkeeper there she informed me that they were having trouble getting paid & presumably that's why it took them something like 4 months to pay me for a half-dozen rundowns (that were ordered on a RUSH basis).  From that day to this they haven't contacted me about doing any work at all, which is a good thing as I don't want to have to go through that experience again.
