Looking for a simple shopping cart solution

Here is my use case...

We would like to let the visitor add one or more items to the cart, but do not need payment processing. In the end, the visitor would submit the request and receive quotation/offer for the selected items.
In the simple scenario, the quotation could be generated offline, manually.

We do not need complex e-store and product pages. Item could be added to the cart by clicking the button which may be added to the existing pages manually or through short code.

We would like to skip complex e-store, payment processing, stock management, etc configurations and make things as simple as possible.

Is MarketPress suitable for such a simple scenario?
Are there any other simple solutions matching our needs?

Thanks in advance.
