It sounds like you have a great background to begin with, and I think it's a good idea to contact some publishing houses. I would look for ones that have had some of their books already translated into Spanish. Also, see if you have any contacts that have written books. My wife's uncle came to me one day and said that he had written a book and wanted it translated. Granted it wasn't a best seller or anything but just having that experience is well worth it.
