Wordpress Development Required for WooCommerce

I am looking for an experienced freelancer to help customise a Wordpress theme I am putting together. I am converting this site ([login to view URL]) into Wordpress using Woothemes and WooCommerce. There are 15 styles of canvas, as well as a photo to canvas option. At the moment they are using a single ordering page, but I would like to add this feature to each individual item. So for each canvas style it will have a product page where the user can select - product size (adjusts the price displayed) - how many people do they want in the portrait (1-4 with the price increasing for each) - How many portraits do they require (again the price adjusts to reflect their choice) - If they want an optional special coating (choice of 2 coats with the price changing to reflect their choice) - I then need them to be taken to an area where they can select the colour combination (by selecting from a choice of examples. - They then to to select how they are going to send their image. If it is online I need an upload facility. Once they have added to the cart and have finished adding images I need it linked up to Paypal. NOTE: I need customers to only pay 50% of each canvas so need a partial payments system. They pay the other 50% once the canvas is completed. This is the only customisation I need doing as I am doing all of the design work. I'm looking to work with someone long term so will be using this to see if we can work together (I do have a big on-going project lined up for November). Thanks.
