Script to Handle .psd files on Server Side change Smart Objects

Hi! I need a Script that does the following: Someone will upload any Image via a website. (Simple file uploader) On the server side: 1 - Get the uploaded image 2 - Open a .psd file that is already on the server 3 - Replace the Smart Object of the .psd with the uploaded image 4 - Save the final result as .jpg and return this image as final result to the user Done If you know how to do that, please contact me. I have a project for you. Can be done with Javascript, Node, Php or other languages. Please let me know total price for that and amount of time you need to complete the task. This is an example of how it should work: [login to view URL] There is also as attachment a sample file you can use if necessary to test something. Thanks
