number of onto functions

Q: In how many ways can 7 different jobs be assigned to 4 different employees so that each employee gets atleast one job and the best employee gets the toughest job.
I suppose this is equivalent to finding number of onto functions from a set of 6 elements to a set of 3 elements, which I get as 540. Am I right?
