It might be easier to have a quota or a teir system. For example 3 sales/wk = $300, 6=$700, 12 = $1500 and so on. Most good sales people will quickly look in the middle and say, thats easy to hit--and then look at the top bumps and get excited. A good commission structure should allow you to hire many sales people at the same time (since you don't have to pay them if they don't do anything). However, if you don't have a good handle on what your costs are or how much profit each sale is worth you will bleed to death.
