For anyone who speaks Spanish: need help with locating a local newspaper

I have a fairly minor research question for work, for anyone who speak Spanish (it’s confidential, I apologize in advance and wish I could share why I need the info):

I have to find a newspaper that publishes in the Mexican municipality of Comitan, Chapias. I have two semesters of college Spanish, and am not nearly fluent enough to research this via google. As far as I can tell, there is no local newspaper in the municipality of Comintan in the state of Chiapas of Mexico, near the border of Guatemala. If there is a local newspaper, or one who publishes in a nearby city, can someone direct me to a phone number to call that connect to their want-ads or publishing department?

Again, sorry for the vagueness, but my translation skills are failing me at this point.
