I can highly recommend Todd Goings of Marion, Ohio.  He has done very
fine work for me and has an excellent shop capable of doing the multiple
units you are describing.  The last address I have for him is

  Todd Goings
  Carousels & Carvings
  2209 Marion-Waldo Road
  Marion, OH 43302-8307
  (740) 389-5842
