Simple and clean ajax draggable/droppable/sortable frontend UI

Looking for someone to create a simple and clean UI made of droppable and draggable images. We have 5 set of images that the user will be able to drop into cells. The same image can be dropped multiple times even into different cells. We would also like to have the cells to be sortable. We want to be able to do some checks/calculations each time an element (image) is dropped into a cell (those calculations will be done by our backend php script, we just need the whole cell (or whole form) to be submitted and wait for a return value Once the user has ended filling the cells as he likes we need to be able to submit the whole page to a php script that will do subsequent operations (we will take care of that)
