Similar to eBay turbolister and shipping wizard for phpprobid

I'm looking for 3 things to be done in my phpprobid site. First one similar to eBay turbolister or auction manager from [login to view URL] clone, an application software user can download from my site install on their computers and create and manage all their listings. With a couple of new feature includes. More details later by email. Second thing is a shipping system completely incorporated with phpprobid just like eBay shipping wizard. If you know eBay you know what I'm talking about. Seller choose method of shipment and everything is calculated by itself and end user are able to see carrier and price already on the item listing As well as on invoices based on their zipcode location without having to use the weird shipping calculator included with phpprobid. And the last thing is a new category add-on when creating a new listing, Phpprobid comes with auction and buy out ready but I want to include a new form of listing but won't give details here because I don't want competition having included those features on their websites. More details upon request. You must know phpprobid code well and be able to communicate in English. Non-Disclosure Agreement is required
