Is there any gearbox that could get me close to this ratio? Unfortunately, the AM Planetary gearbox from AndyMark is only 3.67:1...

Thanks for the help.
You could also use the AM Planetary and do the rest of the reduction by a set of roller chain or timing belt sprockets from the gearbox output to the roller. With a 12t sprocket on the AMP gearbox output and a 40t sprocket on your intake roller, you could achieve an overall ratio of 12.23:1.
