There is a Moyer Farms in Missouri. I'd make sure that whatever you use does not look like their registered trademark. Nobody likes paying lawyers, but you should really contact a someone who does intellectual property and spend a little money to make sure you don't come up with something that infringes or dilutes someone else's mark. What if you pay for graphic design and advertising based on a logo, and then you get a cease and desist order from someone's lawyer? You're going to be out whatever you spent and have to pay to start all over.
