This clearly isn't the right mailing list to seek help with that.  More
about that below.

Surprisingly enough, many things turn out to have uses for which they
were never designed.  Of a certainty, you're correct that Prof. Moglen
and Richard Stallman most definitely never designed the GNU GPL to be a
component of a proprietary-software business model.  Notwithstanding 
that fact, it's definitely feasible to do so in some circumstances -- as
I believe I mentioned earlier.

Now, people here are generally (if somewhat vaguely) sympathetic to your
desire to find a business model that works for you, because we're
generally pleasant and agreeable people.  But sooner or later we'll
tend to come back to an inconvenient fact -- that this ultimately is
just not the "Improve Glen Low's Business" mailing list.

However,, if you want to start such a list, I can recommend some good
open-source software to run it on.  ;->
