Create an eCatalog from a PDF catalog

I have a PDF catalog that is not user friendly for changes to products (delete, add, modify). I need someone to create a new eCatalog using the information from the existing PDF catalog. The new eCatalog must allow me to remove or add products easily, without causing alignment problems to the other products and text. I must be able to easily change photos, text, pricing, etc. I would like the ability to make bulk updates with Find and Replace style editing. The eCatalog must give the reader the ability to go directly to various product categories (shortcuts to categories). The reader must have the ability to print individual pages or the entire eCatalog. As you will see from the existing PDF, each product consists of the parent and then one or more child products. A child product might be specific color choices, sizes, etc. I will want to approve of the layout style for the parent and child products.
