I think you're going to have to try to resurrect the non functional device since I don't think you'll find a repair or recovery service that will be able to save what's stored on the device.
The first question to answer would be to find out what happens when the device is plugged up to the computer. If the computer recognizes the device and if ActiveSync or WMDC recognizes the device, then you might be able to use ActiveSync/WMDC's explore option to gain access to the device to copy over the stuff that's there to the computer.
Do you know what make & model windows mobile device it is?
