Web Development: Plone / Python Dynamic Web Pages

What I need: User pages for an existing Plone 4 website. Dynamic content management pages integrated into an existing Plone4 website. See attachment. We are looking for interactive feedback and design input as the project develops. What I already have: Already have an existing Plone site with static pages, navigation, registration, and security. Icons and graphics exist but some additions may be required. Other context/requirements that providers will need to know: The pages need to be easy to read and use on desktop browsers as well as remote devices. Tie into Amazon Market Services for commerce is required. Specific expertise/background that I am seeking: Experience developing data structures, dynamic pages, and mobile views in Plone4 or Zope applications.
