Looking for plugin to post comments on my posts

I am looking for a plugin that will automatically post a bunch of fake comments on my own posts. It is for an affiliate marketing website that has over 7000 products on review and I just want every post to have some type of “awesome product!” “hey thanks this worked for me!” type of comments. Just like 30-40 comments on each post.

Is there anything out there like that already or where can I find a person to write one? 😀
