ASP.net / SalesForce Integration

We are in immediate need of a professional who can build ASPX pages that integrate with SalesForce.com. You must have experience working with the [login to view URL] web services, and must be able to turn this project around quickly. We currently have a UK-based client that needs to provide SalesForce functionality (lookups, edits, adds, deletes) via an ASP.net application. The project has already been started, but requires a professional to work on it quickly & full time to integrate five areas of SalesForce into this application. The integration would include the ability to search through the SalesForce data for the specified areas, view the detailed information, and also see and drill down into the sub-views. As an example, one area is 'Clients'. The user should be able to view all Clients in a list format and also perform searches or see all clients by letter of the alphabet. When they choose a client from the list, they then can see detailed information on that record, such as: -Name -Web Site -Region -Address -Description -Phone -Fax And then also as part of that view, there are summary sub-views, such as: -Open Activities -Related Contacts -Opportunities -Resources And each of these sub-views is clickable and can be drilled down into. If you are familiar with SalesForce (which you must be for this project), then what I am writing should make some sense to you. We are looking to start immediately. Thank you!
