CRE Loaded PSD Code and Updates

I have an existing CRE Loaded ecommerce site that I am redoing on a test server that I need some help with: 1) I have a PSD I need coded to the CRE Loaded store. The design is pretty basic nothing too difficult. 2) I also need a shop by size feature that will pull from the product options - so if a specific size is out of stock it will not show on the product page and the item will not show for the customer. 3) We need a zoom feature for product images so customers can view the images in detail And that should be it! Prefer someone who has CREloaded experience specifically.....thank you. This MUST BE completed by Friday of this week.
