Android Camera with Filename Renaming

I need an Android app (2.2) that will allow me to: 1- Take a picture 2- Rename that picture with a 9 digits number.... something like [login to view URL] (Best scenario is that once a picture is taken, a full screen keypad appears with the number 0-9, backspace and clear. .) 3- I can then enter the filename , push a "Enter" or "Submit" button and the picture is saved into a Micro SD Card on the device (Samsung Galaxy Tab). We are taking picture for thousands of inventory items and i need to have the ability to do this really fast. You will need to upload the app on the google marketplace for me as well.
