|Have never worked with any of their namestyles, so, no personal experience.|
However, doing a "search" here for "The Notary Exchange" came up with quite a few threads. Here are some, mostly in January and December:
A few positive postings. Some people were paid their agreed-to fee by echeck within a short or reasonable period of time. Many negative postings. IMO, some of those negative posts were from people who haven't worked with them but were basing their opinion on the companies' prior reputations.
If you do decide to work with them, please let us know how it goes. NOTE: Remember to invoice immediately. From what I gathered in those posts, this is most important.
