Custom Code Written for Website, Upload Picture then it shows on product.

So our main platforms we use are Wordpress and Drupal. We prefer Drupal so would like this code to be easily integrated into our custom drupal build. Here is the problem, we have a client that has a product that the user uploads a picture and it overlays in the blank spot of the product and needs to show the user the updated product with the uploaded picture over-layed onto the product. Also there will be a Text Area that will be over-layed as well and should be updated in real-time before they order the product. ***VERY IMPORTANT! - After Customer uploads photo and inputs text this needs to send the finished graphic via email in .pdf or .jpg so it can be printed on the product. We will be using Uber cart for the shopping cart so really we just need to have it give us a finished product/picture to be printed and show the user the uploaded picture and text overlayed onto product. Please if you do not understand this project then ASK questions before bidding. Only bid if you are sure you can finish this!
