Contact form for availability in product page (Magento 1)

I am looking for an extension paid or not that will give me the possibility to ask a question about the stock on a product page.

The idea is the following there are special products made to order where the stock information cannot be maintained in real time but it is necessary to discuss with the supplier. A potential customer will click on a [Ask for Stock] link and in the modal window fills in Name, Email then select the Options of the product that interest him such as Color, Size. If he wants to send additional information/requests then he can fill the Message field. Then he clicks [Send] and the form reaches the store owner by email. Nothing is recorded in the database, no special section in Magento Backend, just a basic and efficient functionality for asking a question.

Any help is welcome.
