Showing message instead of making payment after checkout

[shenkwen]

Hi everyone,
    I'm very new to VM, am using VM2.0.6 now. I am trying to build a whilesale site, the difference from other online store is that I only want the customers to place orders online without making payment. When I receive the notice of an order being placed, I will review the customers' information manually(offline) or contact them.
   So, when the customers click "checkout", instead of redirecting them to payment making page, I just want the system to show some message to custmers like "Your order is being processed", and give me a notify including customers' information(name,company,payment method, shipping address, etc.) in any form, which could either be an email or a submitted form that can be reviewed from VM's backend.
   Is it possible to achieve that? If yes, do I need to play with PHP and javascript, or I can simply make it happen through VM's backend? I have very limited PHP/javascript knowledge.
