Good question. I'm a car salesman and have searched several times, but nothing comes up on the internet. so I proposed my own...St. Felix of Cantalice...
St. Felix was the official beggar for the Capuchins in Rome in the mid 1500s. The Saint of the Day site says
"As he made his rounds, he worked to convert hardened sinners and to feed the poor as did his good friend, St. Philip Neri, who founded the Oratory, a community of priests serving the poor of Rome. When Felix wasn't talking on his rounds, he was praying the rosary. The people named him "Brother Deo Gratias" (thanks be to God) because he was always using that blessing."
That's basically what I do: jump through hoops, beg for business, keep a "thanks be to God" attitude...and...pray the rosary (prospecting)....
