[paperman]

I would take the approach that salesman that are any good and worth their salt are employed by someone.
that was any good, i think they generally tend to be people In my job i have come across many salesman over the years, selling all manor of goods and services, i can hand on heart say that i have never come across what seemed like a commission only salesman who aren't salesman 'giving it a go' - perhaps they have been given the 'you too can make £2000 per week using our structure' kind of talk.

If you want good salesman, then commission only is not the way to go (in my books)
