Develop TTL --> SD Card Logger

We are looking for someone to develop a device that will take raw serial data and write it out to a FAT based SD card.

The device needs to:

-Log the serial data to the SD card (naming the output files by date/time would be optimal)

-Have an input pin which can be switched to ground to enable the device's logging

I can provide:

-Detailed information on the serial protocol

-Any other information needed for establishing the serial connection

I would love to discuss this project in greater detail.

Additional Information:

Power requirements:
-Input power for the device will either be 5v or 12v depending on how the final design works out.

Display will be limited to:
-LED 1 Indicated device is powered up and operational
-LED 2 Indicates logger is active

I am looking for the following for this project:
-A schematic of the device
-A working prototype

-The device should optimally be smaller or equal to 2" wide X 3.5" long.

When we initially posted this ad we were not aware of the level of response we would receive and were not adequately prepared with the project scope.

We have now drawn up a scope document and we request that you look it over and let us know what you think.
