You can contact your state's local unemployment office -- they might just have some names of people with the skills you need seeking employment.
Possibly the Farm and Ranch Freedom organization might have a suggestion. See their website:
http://farmandranchfreedom.org/content/about-usOther than those, here are some other ideas for people or sites you might contact for suggestions: your agricultural extension service, the nearest agricultural school (college), the leader of any local Future Farmer's organization -- and be sure to post it on any close Craig's List.
Be sure to ask around your community about what other people have done in such circumstances -- pastors, priests, local public officials, doctors, veterinarians, attorneys might have such information.
Keep trying. You never know where help will come from.
Really, best wishes to you and your family members!
