cabcart

I'm webmaster and I have a long time web project with a lot of tools to set up and develop but i want to develop the project by levels and i want to start by configuring a shopping cart that i include in my website and rent to my customers to set up their sites and sale their products. After, I want to propose to make a estore (like [login to view URL] for example) with the global payment solution and esite based on the cms. I used drupal for the cms and oscommerce as shopping cart but i need tools more friendly and adapted to the end users. I have others tools to develop but i'm looking for a long partnership and if you are interested by the project i can send you the features i need with the shopping cart.
