Well for the things in life, I've learned LaTeX. I'm not a guru, but I think that I can perform some good quality documents. I want to know if is possible to get a part-time job in an editorial, journal or something like that. I'm outside of the U. S., but I think that perhaps is possible to work by Internet.
As mentioned in the comments, this is probably not an appropriate forum for this kind of question. However, if someone comes across this might be a useful link: Where can I find people for hire with LaTeX skills and designer skills?
