BlackBerry App using WSDL

I work for a software company that develops Facility Maintenance Tracking software. People create Work Orders in our system to track work that has been done or needs to be done. The software is written in Visual Basic and ties to an SQL database we currently have a .net application that runs on Pocket PCs. We would like to develop an application for the Blackberry handhelds. I need someone to write a webservice (WSDL) that will tie our database to MDS services MDS studio will us this to create the application to connect to the datasource. The project can include the complete application depending on price. Its up for suggestions. The application User will recieve a notice, he has a Work Order> he will then open the Work Order update the time he spent on the work order and then Complete the Work order. Pretty simple our database structure is very simple and properly labeled. i am just confused on the webservice end how to call the database. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
