Half finished Magento store needs to be completed

We are an established e-commerce company. Recently we started to move from a Miva platform to Magento and engaged the services of a developer. The Developer completed the project and we realized that we are missing some key functionality/design so we are revisiting the design and looking for a Developer partner to complete the project. Here are the requirements: 1. Fix the css stylesheets so that product information can be displayed correctly. Currently the HTML entered for product description is not being rendered properly 2. Create a CMS block for brands/manufacturers on the product page. 3. Correct the shopping cart feature so it shows products added in the shopping cart. 4. Correct small layout problems in the checkout screen 5. Add a CMS block for related products to the product pages 6. Create/edit a CMS block for the home page so enteries can be inserted properly 7. Fix [login to view URL] so that product options layout will adhere to the product pages. (currently if you add an option/attribute to the product, the page layout becomes skewed) 8. Provide documentation on how to change varous aspects of the home page 9. add zoom-in capability using ajax in the product page for the product image 10. Install and configure 5 extensions (We will provide the extensions, you should install and configure so they work properly) Once the project is completed, we need 3 business days to be able to test the functionalities and make sure everything works properly. The bidder must provide at least a 10 day guarantee/support of their work after project completion.
