A poster on the self-publishing list is looking for a typesetter who can handle a dual language book, Arabic and English. I don't qualify :<) This list with its international membership seemed a good place to inquire.
If interested please drop me a line and I will forward to the other poster.
I think I qualify: I have been studying Arabic during 5 years as a third language (although I've never had the opportunity to use it, so sadly enough, I can't really speak it).
In the past few months I have used ConTeXt to typeset a lot of things (and before that, LaTeX for many years), but no book yet.
Anyway, this is to say I'm interested in the project.
