Revamp our wordpress magazine design

Hello all, We are looking into someone who is able to improve and make modifications to our wordpress design to make it better. We don't need modifications in functionality, as everything is working great. But we need to have a different feeling to the website. Like a update to a newer version. Demo can be found here: [login to view URL] Please mention in your proposal how can you help - as I said, I don't want a different theme, we need to use this one but perhaps with newer version. We just want the homepage, the other pages are all good. P.S: Please only bid if you are serious, as we are not looking to waste our money and time. Thanks all.
