Automator - jpeg and raw file movement

OS X 10.10.3

4k iMac and early 2009 Mac Pro

I have 2 file locations. Location "A" has jpegs and Location "B" has RAWs. Location "A" has ~700 images that are to be edited, but location "B" has ~10,000 images (most will not be edited).

The files in Location "A" have a matching RAW file in Location "B". The file name is the same, but the extension is .CR2 instead of .jpg. I want to move all the corresponding RAW files from Location "B" that match the file name of the jpegs in Location "A" to Location "C" (any user input destination).

Is this possible with a service? Any help in writing this service would be appreciated. I'm not sure on the best place to start.

Thanks
