Custom Prestashop Module - repost

Custom homepage module to display 20 plus products in a grid (jquery masonry) must be able to select what size picture to display on the homepage from 5 predefined sizes, when each product picture is clicked it should open in lightbox with thumbnails of another 4 associated products that when clicked change the main picture in the lightbox. It's hard to explain what I require, however I can send you a link of what I'm looking for. The module must be compatible with Prestashop 1.5 x and be responsive. Please note: I wont award this work or any future projects to anyone that can't speak on skype, I like to talk to people I'm working with
