Volusion - Sign up to Our Newsletter Pop Up needed

I have an online store with Volusion and need someone which is familiar with the volusion interface to create an add on feature for me. I would like to get a pop up added onto the homepage, which prompts customers to sign up to my newsletter in return for a store credit. This is how I would like the process to work 1. So when a customer visits my site, a pop up shows and asks customers to register. 2. Once the customer has registered a thank you is emailed to them with a code for 15% off their purchase for one time use. 3. This applies to new customers only. I would also want the following: 1. An option to close the pop up box incase the customer does not to sign up 2. Ensure the pop up only appears once to that IP address, so if the customer revisits the site it does not show up again. 3. The customers details to be set up as Opted In to receive all newsletters 4. Customer can only receive this offer once per email address
