Have you looked into any home brewing equipment? You can get brew pots with spigots, food safe plastic buckets w/spigots and tubing to run to the bottles. It might be slow going, but it's sanitary and can be done in your kitchen. I put my bottles in a large plastic tub to catch the overflow and keep clean-up simple. If you don't have a homebrew shop near you there are several online sources for this type of gear.
