Pre Order Mod Needed

I have an oscommerce based webstore ( heavily modified) i am looking for a skilled person or company to write a PRE ORDER module for my store. eg : if an item is out of stock i need to be able to allow or deny customers to pre order the item "if i am accepting pre order for this item of course", there would need to be a pre order message displayed stating that the item is for pre order only and a date stating the item would be available on for delivery etc.. i would also need to disable the pre order for individual items. eg some items that go out of stock, i dont want to allow a pre order as we might not be re stocking that product again, so if i wanted an item up for pre order i could allow or deny it for that individual product. please see the attached file for a rough idea what i would require, or if possible replace the out of stock button for a pre order button for that item only, i have seen this option on another website. if you are bidding on this prodject you must be 100% confident you can complete the job in hand, you must be very experienced in php and oscommerce , if you need to view my site i will send you a link via email.
