No that is the way to go, but having the statistical information really will not be what makes the sale. And if you are going to be dealing with small businesses, then you are going to have to end up creating the banners and everything for them more than likely. And of course you have the payment collections to deal with and the renewals.
Take it from me, this is no small task that you are starting. But you will do better in the long run, but it will take a while to get it going is all. And the stats will not make the renewal, especially on bb's since the numbers will be so bad as far as percentages go, you will have to do a little more than just sending out the stats to get them to renew on a regular basis.
