Create Logo and Wordpress Blog

Hi - I need a logo designed and also a wordpress blog site constructed in line with the logo. It will be a simple blog, but needs to look very classy and professional. The logo is also needing to look very good. I have some examples of blogs which I like and would like to theme around this. Also would like the theme to be unique, no templates. Finally, the backend needs to be simple to use, in regards to adding post, and pictures etc Thanks
