Help needed for my son (Cancún)

Hi, my son Scott is currently living in Playa del Carmen with his mexican fiancee Sandra. Scott is currently working in a call centre for commission only but they have just found out that Sandra is pregnant so he needs to find more reliable, professional work. He has worked in sales, as cabin crew, administration and has a british university degree in computer science. They have had a really rough time of it recently and could really do with any help or advice anyone can offer them. I really would appreciate any help as well. Thank you, Jackie
