Affiliate Tracking Wordpress

I have a Worldpress Website- [login to view URL] I want to use affiliates to get new sign ups, I use paypal, will offer 1 week free, then £99 per month through Paypal buttons. I want to have a system to allow me to track affiliates so I can pay commission. I installed Idevaffiliate but in all honesty I dont have the expertese to make this work. I need a solution to allow me to have affiliates and provide them with commission stats, using paypal recurring payments. Can you help?
