Wordpress affiliate program plugin

The plugin will:
Generate and track affiliate links (website.com/sfas - currently using Pretty Link)
Track if the traffic sent from affiliate link converted via paypal (currently using Nice Paypal Button Lite) +for how much

This is currently how it looks: http://declanjason.com/event/eclectic-night/

You can suggest or install a better plugin that will do this. Also, it would be nice that when it comes to check out (buy now), that the user can input quantity.

Looking to spend around $40

Let me know via inbox!

Thanks

I can do this! Sent a pm.
