Audiobook Download Site in Wordpress

I need an experienced Wordpress developer to create a sites for an audiobook download site. There will be a ".com" site for fixed internet downloads and a mobile ".mobi" site for mobile usage. Design, structure and navigation should be simple & impacting and reflect the classical nature of this content driven site. The design is friendly without pics, buttons or gimmick's to ensure mobile compatibility. There is generous white space which lets you focus on the content. Global navigation is bold and clean. Older demographics should be comfortable with it.(e.g. [login to view URL]) WP acts as an easy to operate CMS; all blog functionalities are turned off. The site will offer about 200 low-cost classic audiobooks and short stories. >>>>>> Functions/Plugins for the .com site <<<<<<<<<< Administration of permanent ad's (e.g. [login to view URL]) PayPal shop integration(e.g. [login to view URL]) Plays prelistening files(e.g. mediacaster) SEO plugin(e.g. All in One SEO Pack) Statistics program (e.g. Firestats) .com site should work well on mobile devices as well (no sidebars, adapting widgets for use without sidebar, no fixed width, plain text, structure through fonts) >>>>>> Functions/Plugins for the .mobi site <<<<<<<<<<< .mobi site with [login to view URL] .mobi site validates with XHTML Mobile Profile([login to view URL]) .mobi site should work very well on mobile devices AdMob and Google Mobile Ads integration I need a good wordpress back-up - plugin Both sites should pass w3c validation and css validation. The site is copyrighted to me. >>>>>> OPTIONAL/Server/installation/ <<<<<<<<<<<<< I need a solution for country recognition and redirection to country specific sub-domains. Installation of google apps at a new server The attached [login to view URL] gives you a general idea of the site. I am looking forward to your quotes, questions and work samples, Andreas
