Développement solution e-Commerce

Bonjour,
Je représente une jeune société qui souhaite présenter et peut-être plutard vendre ces produits sur le net. Pour le moment, les produits sont présentés avec VirtueMart mais cela ne correspond pas totalement aux attentes. Est-il possible de développer un module permettant de faire évoluer VirtueMart vers les fonctions ci-dessous sans se bloquer la possibilité d'installer les mise à jour du produit.

Product short description :
Instead of show only a short description of my product in the category overview page, I need to show all of this :
- Short text.
- Facility of culture (icon).
- Type of utilisation (icon).
- New product or not (icon).
- Adult size (icon).
- Place of culture (icon).

General description :
In the product detail page, I need to show all of this :
- Full text description.
- Facility of culture (icon + default text + specific text).
- utilisation (icon + default text + specific text).
- New product (flash icon near to product name).
- Size (icon + default text + specific text).
- Size disponibility (available in 1l, 5l, ...).
- Place of culture (icon + default text + specific text).

Search or browse options :
I need a possibility to browse or search products like this :
- List all products.
- List by category.
- List new products.
- Search by options define in general description (facilty of culture, utilisation, adult size, size disponibility, .

Informations :
All the options facility of culture, type of utilisation, new product, adult size, place of culture, needs to be identified by icons in the overviews and by icons and text in the general description. Each value of this options need to have a different icon with a different text.

The value can be for example :
- Facility of culture : very easy, easy, hard, very hard with one different icon for each possibility.
- Type of utilisation : it's necessary that I can define 5 or 10 different otions.
- New product : I want that a icon show that one product is new for X days or show last X products like new.
- Adult size : very small, small, normal, big, very big.
- Place of culture : possibilty to define 5 or 10 place of culture.

I want that if a user move is mouse onto an icon, the description appear. For example if a user move is mouse onto the icon that define de small plant, a text should appear saying "small plant".

I need that all the options (facility of culture, adult size, ...) can be edited by an administrator.
If possible, I want be able to show the last products in a newsletter.
