Auto content managment system script needed

I'm looking for someone to build a script for my blog that will generate content from other news related websites to my site so google can read this content. example: cnn released a new article about real estate- my website will update it self with the new content automatically. Basically I don't want to deal with inserting content to my blog, so instead I will have a content management system that will do it for me and I will always have fresh content in my blog.
