Members Replace Affiliate Links on My Site with Their Own

I have a website (www.mysite.com) that sells an existing affiliate product which I will call x. I want to create a members area where members can put their own affiliate link for x in the members area. After entering their affiliate link for x, they will get their own custom links with their affiliate id to my website (www.mysite.com/?id=123) This link will automatically replace all afilliate links for x on my website with the members own affiliate link for x.

That way, when the member shows someone my site, they get credit for the sales of x instead of me.

Is there a plugin that will do this? I’ve searched and searched for something that will do this and I can’t find anything. I’m not sure what to search for.

Thanks in advance for the help!
