Looking for Tumblr Blog Design

Hello,

I am looking to get a basic design done for a tumblr blog. I'm quite fond of the default tumblr theme (as you can see on http://andrewryno.tumblr.com/). I'm a fan of usability over 'pretty' designs, so I'm just looking as minimalistic as possible that presents the data over everything else.

Please list your prices and turnaround times as well as a link to your portfolio or at least some previous work.

Thanks,
Andrew
