News Aggregator Theme PLEASE HELP

I am trying to accomplish a themes blog that I can gather information in various places about a single subject and combine it together for the viewer to get more complete information. I am looking to get a site that has great easy access and is user friendly so they can jump in and go to town. Can anyone direct me to a theme amongst the thousands out there that will help me to accomplish this?

I am here to answer any questions if anyone is confused about what I am trying to do. I have also posted an image using MSPAINT to give an example of what I’m shooting for. It doesn’t have to be a full Wordpess theme because I was told I could even make something as a static HTML page and then inline frame the blog with hardly any structured theme to it so it can all come across good and user friendly. Does anyone have an idea of what themes I can start with to help out with the creation of this?

I would be willing to give credit for any help with this theme. I already have a graphic designer and a few programmers that are all willing to help me. I just wanted to come to your community and get your professional inputs on what I should do. I have mostly decided to go with WordPress but my biggest challenge is to make a theme that will fit my needs. Thanks in advance for any help you can give me!

This is the basic idea so far:
