Create Prestashop module / Edit an existing one

Based on a module that i will give you, i need someone to create something ressembling this module, or transform it and add some functionnalities. The module will allow the customer to edit an existing product, by choosing the color, adding a text to it, etc.. and the module will be able to calculate the price automatically, based on the surface used, the color, the size, and few other options I you already have a preexisting module that fits this description, feel free to show it, and i would buy it if it correspond to my needs, or ask for modifications. This project is rather urgent, so i would need the work to be done before the end of the week Thank you
