If you are ok with unpainted ones you need to look for the Hornby ones, they are OO scale which is slightly larger than HO (I mean really only very slightly) and normally come as a pair, driver and stoker. These are packed with each loco normally, but I think you can get them seperately.
Or if you can wait until my next Daiso red cross parcel mysteriously appears on my door step it will have their set of drivers/train crew in it
