In 2005 Guillermo Huesca served as host for Trato Hecho, the Spanish-language game show where everything revolved around trading. Thousands of dollars in prizes were put into play for each show, and any member of the audience could end up being a lucky winner. Contestants brought items from their homes, hoping to trade them in exchange for prizes.

Contestants were encouraged to come to the show in disguise, wearing costumes that would make them stand out from the rest of the crowd and get them noticed by host Guillermo Huesca.

Trato Hecho was all about trading and making deals for the best prizes. The stakes got higher and higher as the show went on, and in each show the two biggest winners were put to the test to see if they want to risk everything in the hope of becoming the biggest winner of the day.

Trato Hecho was seen weekdays throughout the United States on Univision cable, satellite and broadcast stations.
