I am considering setting up an affiliate system on my websites paying for leads that convert.

My average sale for kitchen units is between R55 000 ( $ 2950) and R120 000.($6440) I would be willing to pay 2% commission for orders placed. This payment would happen on completion of installation and payment received.

I am busy building an affiliate dashboard.

My thoughts are that the dashboard would have all the following info
I would supply the following information to every affiliate, referal, cookie expiry, lead status (referral, rfq received / quoted / accepted/ in progress / completed), Value, commission, total commission earned, current commission due, payment made

Also would have images, banners and the like for download, suggested keywords.

What traps should I be looking for, I don’t want affiliates to be spamming and devaluing my brand.
