CreLoaded Pro With Contributions

I have Creloaded Pro White Label. I need someone who can take this and added the following contributions and ensure they are properly functioning: Sold Out Button Contribution (this is an OsCommerce Contrib that needs to be put in, or if you have one of your own or another you know of that will change the "buy now" or "add to cart" to "sold out". This function needs to work in all pages where a product would show up the [login to view URL] page, the advanced search, the shop by price page, the product list and category pages and the all products page. We've had 2 attempts at installing this with previous workers that don't work. This will be tested on all these pages so ensure before you bid that you can do this. Recode the X-Sell page to be sort by the product Name not the product ID Add in the Quick Updates Contribution (I have a copy for you or can point you to where to download it) and code it so that both price and stock can be updated quickly. I need this done professionally, I need you to have vast experience with CreLoaded and Creloaded Pro preferably. I need this done quickly within the week, which shouldn't be a problem as to add these functions in shoudl only take a few hours. I work with CreLoaded I'm just not a PHP coder. I'd highly consider someone if they can show me a creloaded shop with a functioning soldout button running that they coded!!! Payment will be 50% upon delivery and %50 upon testing and correcting of all errors related to these contributions.
