Meet the detective at Taco Bandito
Chaz (the investigator) tells you that if he finds the secret the source doesn't want revealed, they will keep quiet. To convince Chaz to help you, you can either pay him 
1000 or ask nicely. If you ask nicely, he will tell you that he’s making an ad for his agency, if you appear in the commercial, he’ll cut your fees down to half price.
