I have a chapter in my book on beach vendors about women and have co-authored several articles in Spanish about them. I think the articles are available on academia.com and on ResearchGate--except one that was published in Research in Economic Anthropology. The book is Economic Life of Mexican Beach Vendors: Acapulco, Puerto Vallarta, and Cabo San Lucas.
I wish you all the best with your interesting project, and hope to read one or more of your publications on the subject.
