pretty much. thought about it a little more and would basically say that clientele is just the idea that describes who the clients are. the clients are actual individuals.  
  
 the answer to 'who is your clientele?' would be something like, 'they are people with X and Y needs, and willing to spend Z amount of money.' 
  
 the answer to 'who is your client?' would be more like 'Jeff. His bill this month is $98.45 and it is due on the 26th of each month.'
