Tamales for Christmas

My family has a tradition of tamales for Christmas brunch forever. This year, people are too busy or sick to make them as it's like a 2 day process, so purchasing them see to be the only option. We bought them from a lady who made them out of her house a few years back and it was delicious but she doesn't do it anymore. Does anyone have the same traditions and know where I can get my hands on like 15 tamales on Christmas?

P.s I'm talking the tamales wrapped in green banana leaves, like the Guatemalan ones, not sure of the name.
