I need a review and design enhancements for my online shop page.

The shop language is german. Find all bugs in design, language texts, optimizations of  the workflow and the ui. For example a designed dynamic shopping cart popup where u can see the current content of the shopping cart... Or to shorten the payment progress or shopping cart page.

Changing the magento shop system according to the review results.

The project partner should have experience with working on german text.
