Complete Wordpress Website in Japanese

I am developing a website for my business here are my requirements First, the front-end must be in Japanese, this is a website for Japanese consumers Second, the back-end must be in English, as I will be managing it. We want a minimal look, we like this website in particular [login to view URL] Tasks -Design website in wordpress with following pages, Home(Static Front Page), Store, Blog, About Us, Contact Us -Embed Wazala Store -Set up SEO and Google Analytics -Connect to Twitter Account -Must be EASY to USE, please provide instructions so that I can manage it after you hand it over. Freelancers who can demonstrate experience on similar projects will have an advantage. We are a start-up so this project needs to be done cheaply and quickly. If you do it well we may have some more webmarketing work for you in the future.
