PLEASE HELP!

Hi,my name is Teresa and I am an American and my husband is Mexican.I was reading about ur weddings and had a few questions of my own.Hope u guys can help me.My husband and I was married in the US 10 years ago and now we`d like to renew our vows by marrying in his country down in Mexico.We`re not really sure exactly where would be the best place to do it and we are having a hard time trying to decide.What do yall think?Does anyone know of the cost and procedures for the marriage license over there?
