Create quote page with products with multiple options

Hello,

I want to create a WordPress site with a kind of shopping cart.

I have 4 parent categories and these parent categories has several sub category’s to finally get a product.

I want to make a page where I can choose through the several category’s to finally get the product.

Example:
Parent cat is Server
Frist Sub Cat is Windows or Linux
2nd Sub Cat is File Server or Mail Server
If this is a mailserver and Windows then 3th cat is Exchange full db or Exchange mailbox

I don’t want to display price only get a mail from a potential customer so we can make a customized offer.
This will mean that when his basket is full, we must display a form with all his info and that we get a mail with this info.

Which plugins to use (already tried wp e-commerce and woocomerce).
Are there working (yes really) examples? 🙂

Thanks in advance.
