Hi there,
I have read you project description and understand perfectly what need's to be done.
Please feel free to ask questions before awarding the project.
You should pick me because of 2 main reasons... First of all I am also a Tumblr user and I understand how important is to have a good-looking page and secondly I'd like to use this opportunity to show my skills and what I can do by tying and successfully customizing your theme.
