Customize Quickbooks using SDK

I would like to hire some one with lots of QuickBooks customization experience using QuickBooks SDK. Please bid only if you can do any of the following steps and quote your price for each step. No jokers please. Also, please bid only if you can stay on schedule. 1. Add more tables, screens(data entry), forms, reports & update all SQL logics accordingly and still keep the data integrity. This is not some external screens integrated to QB. This is to modify existing functionality with in QuickBooks Application. 2. Add multilingual capability to QuickBooks. Once I get the quotes then I will ask several questions over the phone and offer project if only after assessing your capabilities. Then I will present all my requirements to determine the final cost / communication/monitoring progress/delivery times. If you like to guestimate work or on how to do it, please download evaluation versions of QuickBooks 2010 & download SDK from their developer network. thanks,
