They are an "agency" that offers to represent writers
for a fee and for persuading writers to buy paid critique
services and editing services from a service that's
described as a "sister" company but in fact is under
common ownership with the agency. It is one of several
new agencies under the umbrella of The Literary Agency
Group Inc. which is a spinoff of the infamous Stylus
Literary Agency (until recently known as the ST Literary
Agency), owned and operated by Robert Fletcher.
The advertise all over the internet, trolling writers groups
and then sending out email to writers saying everything
a new writer wants to hear. Essentially that their script
is very marketable, that they can make a big studio sale,
but that it needs a little work and they have the right
people who will advice and help and keep the integrity
of the original work. for a fee, of course.
And as deadrockstar mentioned, it doesn't matter what
the script is, every writer gets the same, encouraging
letter.
