You actually know the answers to all the questions you posed...you get what you pay for. The better material you give them and the better they are, the better the results.
You will no doubt get many analysts who will try and wrap this up in some form of pseudo scientific formulii, but it really is basic. Contact more people and the chances are that you'll make more deals, even if the product/service is lousy and the sales staff woeful. Add in some forms of quality and then the results will be more favourable.
The best sales people will want a structured reimbursement, afterall, this is your business, so why should they help fund you by not having their costs covered. Why should sales people be expected to share the risks.
Offer nothing and you'll receieve exactly what you've invested, from a sales force who can see you don't have enough faith in your own product/service, or them, to put your money into it.
And target against what is achievable, not what you need to survive. Targets need to be attainable, otherwise instead of being motivational, they are the opposite. After week one you see that you won't hit a monthly target, why bother that month, save any business for the next month. That's what happens on a solely commission based salary.
What do salespeople need to make sales?
Everything you can give them and more.
A targetted product, advertising, marketing support, industry information, samples, admin support, a structured supply/pre/post sales network that works in tandem with the sales people so they can fulfil the promises made on behalf of the company without other departments letting the side down, etc...
And most importantly of all, a boss who they see making an effort to help them succeed.
