Add additional features and programming to existing Magento custom preview module

We have an existing unencripted Magento module that we need to be altered to add additional features and programming. See features we need added below. 1. Can we have the module customized to automatically place [login to view URL] (see attached) in the background once the module is selected and opened by the customer? 2. Then place the image [login to view URL] (see attached) with the card shape cut out so it will mask the cards rounded corners on top of the background layer image. 3. We would like to be able to set place image behind front image as a default for each product in the backend as an option as this would only be necessary for 2 of our 10 products. The others would not require this to be default. 4. We also need an icon so that the client can hide or view the red, yellow and blue trim marks and guide lines which would be placed on top of the other 2 layers see [login to view URL] (attached). 5. We would also like to have the option within the module for the client to be able to download our template in Adobe Illustrator or Photoshop and then upload their completed design while bypassing the need to insert it into the live online design part of the module. Because we offer transparent business cards we need the background to be visible so that they can get an idea of how the card will actually look. If you look at the card comp that we send to our clients now you will understand how the card should look when the customer sees it in [login to view URL] (see attached).
