Develop WP Plug-in - Custom Image uploader

Hi, my name is Brad from Cap-it Australia. We are a very new dye-sublimation company that will be transferring customers photo's onto physical products. We are looking for a WP plug-in for customers to upload, move and manipulate their images to our website prior to placing an order for our products. The plug-in needs to allow users to: - Upload up to 9 photos within a predetermined file size range. - Position the photos onto placeholders, that are overlaid over a product image. - Crop each image to ensure it fits to the set placeholder size. - Drag and drop capabilities - for the user to move images from one placeholder to another. - Insert text over the image (only a few fonts and colours), or insert text with a coloured background instead of an image if preferred . - Change, delete and replace photos as needed before confirming sale. - Once the image placements are confirmed, be directed to a checkout page, and place order / payment . - Once payment is confirmed, send an automatic confirmation that includes a PDF of the customers final product choice to both the customer. - Allow us to download the final images. To clarify our request further, please have a look at [login to view URL] The main difference between this plug-in and the one we would like developed are: 1 - Steps 1 and 2 are to be reversed. 2 - There will be 9 placeholders for this item, not 1. The user will select each placeholder and upload their images directly to each one. They will have the option to remove / replace the image if required. 3 - The user can drag and drop images from one placeholder to another. Where they have 9 images uploaded, if they drag an image onto a placeholder that currently has an image, the images will swap. 4 - There will be 2 options for the client - one with the image portrait, and the other with the image landscape. 5 - We would like additional options to include an option for mobile phones cases (very, very similar to [login to view URL]), and an option for the user to upload and crop a single image over a product - refer to the handtowels on [login to view URL] The website we are building is [login to view URL] - it is in its early stages, but should show you what we are going for. So, to summarise - the plug-in must cater for the following the following products 1 - RUG - 9 images to be overlaid over placeholders - LANDSCAPE 2 - RUG - 9 images to be overlaid over placeholders - PORTRAIT 3 - MOBILE PHONE - very similar to [login to view URL] 4 - HAND TOWEL - one image to be overlaid over placeholder I have included an image that shows the rug (Items 1 + 2 above) I hope this helps you clarify exactly what we are looking for. We are happy to supply any further information to help the quoting process if required
