Vendor Feedback Addon?

I am looking for a system that mimics the eBay feedback system for every transaction where people will have to say whether it is a Positive or Negative transaction with feedback on their communication, shipping etc. I would like there to be a setting for number of days to send out a reminder notification to get the buyer to try and leave feedback for the vendor. This will also include adding a number to the profile for the buyer and seller so that people can see how much business and feedback they do on the site just like eBay.

You might want to look into our EZ Auto Mail addon. You can customize a template to do exactly what you want. Usage docs are here.
