Contact for Shipping Quote

When the request for a quote is submitted using the “Place Order” button, the button remains, and no message is shown to make the customer aware that they have successfully submitted the form.

Because of this people try to submit the form multiple times. Ideally I want to be able to show a message after submission to say: “Thanks for your shipping request. Our staff will process this request ASAP in our opening hours. Thank you for your patience.” and the button disabled.

At the moment customers are trying to send multiple attempts to request an order and are getting frustrated.
