WordPress Modifications

I require numerous customizations and modifications to my WordPress website, it's running the theme "Compare" that has a custom post site "Products" most of these changes relate to [login to view URL] website is [login to view URL] 1. Remove left widget sidebar from "product" pages. 2. Add sidebar on right, unique to each product page, this should have, screenshots, system requirements, quick links. All of this should be customizable from the add/edit product page, when uploading screenshots it should automatically resize and use the lightbox format. For an example of the layout I want (sidebar) and features please see [[login to view URL]] 3. On product page remove the "More" and simply show all the text. Put the following features on each product page on edit/add; • Product Name • Product Price • Product Discount Price • Product Purchase URL • Product Download URL 5. Using the above information, under the product picture, add “Price: $[login to view URL]” and if a discounted price strikethrough the above and put “Discounted Price: $[login to view URL]” below that put a “Purchase Now” and “More Information” button in the same format and colours as the buttons found on [[login to view URL]] Please make this information available in [shortcode] format too, so it can be called from other pages to quickly list this information (such as I will wish to add this to a comparison table in the future)
