Wordpress expert needed PHP -- 2

Adding extra options to deal site. I purchased this design [login to view URL] - Note it is for Wordpress At the moment when someone is buying something they cannot buy more than one item, I want to be able to allow customers to choose more than one, ( but not more than what’s in stock ) Also Currently you cannot add colour options or size options. So when you add a Deal people are limited to what you have on screen. Colour and size would be into effect when selling clothes / shoes etc I want to add extra options so people can pick a size / colour if available. Note: The extra options should not be limited to size and colour. I should be able to add what the extra options are. Example: I might be selling a Memory SD card that’s available in different sizes i.e. 8gig / 16gig / 32gig etc. People should be able to pick what they want. Whatever they select needs to be reflected on checkout so they and I know what is ordered. If there is a shipping charge listed against an item and a quantity of more than 1 is selected one 1 shipping change should apply Example: 2 x Watches – in Black = 4.99 each – = 9.98 - + 1 x shipping of 2.99 – Total 12.97 I will send you the files so you can build / test on your own server. part 2 of this project I need a new widget made based off one that came with this design. If you check the link above and go to the demo site you will see an area called "Recent Deals" this is a widget that displays all the content below .. i.e. all the deals. I was this redesigned so it displayed 3 across and endless - meaning if I have 100 deals the widget will show all 100 3 across and down the page. I've attached an image of how I want the widget to look and also how it should look on the page. I will send the winner of this project the theme in question so you can install if on your server and test it out and design on your server. The site that this is going on it a live site.. so nothing will be going on it without being 100% finished and tested.
