Hispanic Wedding Timeline

I'm trying to figure out the time line for my Ceremony/Reception. The whole thing starts at 7 at night. So the father is going to go to my venue and have the ceremony there he estimates it to be about 30-45 minutes long. I cant see my future hubby till after the ceremony so we have to fit in pictures somewhere in there. I dont really know how long everything else takes. I want to do all the Mexican/Hispanic traditions too though. It all ends at 2am. So I need help on the timeline for the event itself. And for the newlyweds is there something you wish you would have known to add to your schedule.
