Need Magento Product Page Customization/Modification/Layout Optimization

Hi We need to modify the product page of the Ultimo Theme Magento Store (Theme user guide attached). There are following Tasks on the product page: Modification: Additional Information Tab to be merged with Product Description: There are different tabs in the theme"Product Description" & "Additional Information" Additional Information is populated by the attribute values we select for a product. We want it to be placed below the Product description, and without the Tab, just as in continuation. Second Modification: There are Attribute Groups in Backend, but in front these are unorganized, and dispalyed in a single table. We want them to be organised in groups , and group headers also to be dispalyed in front. Third Modification: The empty attributes should not be dispalyed as N/A or NO in front product pages, as well as comparision page, as well as it should show blank , if no value is entered. Fourth Modification: There are some attributed like Warranty, Offer, Subtitle and Delivery Time which needs to be displayed in static blocks at a special position on product page. if any of these values are missing, space should be taken by next customized block. The suggested, and modified layout is attached. Fifth Customization: The pincode checker tool to be integrated, created. Here customer can check if the pincode/zipcode is servicable by us or not. (such can be easily seen on many portals like [login to view URL]) Thrse are the layout modification, as well as customization of product page only. Only experienced developers my apply, and it will be highly appreciated if you can sho the work by example.
