It's very tough getting paid by them.  I did some work in 2007 on a rush basis and it took months and months and months to get paid.  Andrew Veluonis one of the company officers reads this blog on a regular basis and will probably respond to your post.  He is very quick to say that you will be paid immediately, which is what he told me, but it still took a long time to get paid.  There are almost monthly posts about this company's history of slow payments to examiners.  Good luck!
