Round Robin Lead assignment

Round Robin Lead assignment

I am looking for someone that can help me figure out how to weight the leads. Example: I have 20 salesmen and I would like to assign different amounts to them.
salesman 1  = 20%
salesman 2  = 12.5%
salesmen 3  = 12.5 %
salesmen 4  = 15%
salesman 5  =  3%

Etc etc.
