Flores dropped out of school and moved to Santa Barbara, California where he worked at odd jobs to make a living.
While working as a bellboy, Flores read an article about a self-made millionaire who made his money by selling a ball attached to a rubber band.
Flores initially made yo-yos for neighborhood children by hand, but soon started buying machinery to produce them more quickly.
[5] Between 1930 and 1932, Flores sold his interest in his yo-yo manufacturing companies for greater than $750,000, to Donald F. Duncan Sr.,[6] which during the depression of the 1930s was a fortune.
"[citation needed] Taking his own words to heart, he became one of the key promoters in Duncan's early yo-yo campaigns.
During 1931-1932, Flores was instrumental in setting up a large number of the promotions in the cities where the early Duncan contests were being held.
