If you are in Europe, look at the Thorn Sherpa if you are interested in a dérailleur geared bike, Thorn also has some Rohloff models but since you did not mention a Rohloff I assume you want to stick to dérailleur gearing. They are sold by SJS in the UK. I have two of their bikes, a Sherpa and a Nomad, very happy with them. In both cases I bought the frames and built them up but they also sell complete bikes.
Do some internet searches for Santos or Koga.
