WP Affiliate Plugin?

Hello Everyone,
Here's my question....
I need a plugin that's for my affiliate links.

But....

The plugin needs to use my keywords as the link itself - so when I enter my JavaScript or HTML code in the settings menu, it will just link the keywords on my page to the merchant.

And when my visitor's click on the keyword link there immediately taken to the merchant in a new window.

The plugin needs to have a no-follow built-in to it. I currently have one, but it's out of date.

I'll be happy to make screen shots so you can see what I'm taking about.

And can send you a copy of the plugin too for your review, to look at the code.

Perhaps a new one similar or better can be built, with better functionality added and updated on a regular basis.

Thanks,
Harold
