did you do a search, I know the regular one is not working, but you can use the advanced search.
As far as I know if you choose to do a church wedding in Mexico and its a legal ceremony it must be in Spanish. If you are doing a symbolic ceremony then I think you can have a translator.
I think we do have a few people who have gotten married there, but not in the chapel.
I would look around the Cabo area and see who all got married in churches (MerryMe, Edyta, and KarlaV-they are all older members but still check in from time to time, PM them if you have specific questions). Otherwise AmyH is a moderator and getting married in a church in PV so maybe she can at least help you with that portion the wedding stuff.
