contact your local health department, the people who inspect restaurants, they may know of a shared-use kitchen for processors.
Past that, just start thinking and looking at all the buildings in your community that have commercial kitchens-
community center, grange hall, fire hall, church, VFW/Eagles/masonic/Elks, private school, even restaurants afterhours...
start knocking on doors and asking. Maybe get creative in your offers to rent the kitchen. If the church can't make money from the use if it's facilites, maybe offer to trade cleaning services, maintenance, or yard work for use of the kitchen.
Once you find a place, make sure it will be available for long term (occassional) rent. Most licensing agencies will license you for your product in a certain facility and if you change facilites, you will likely have to get relicensed.
Good Luck, let us know how it goes~
