Need Advice for Novice in selling some tractors

[Robert AU81BS]

My brother-in-law passed away unexpectedly recently and he actively bought and refurbished tractors. He left my wife and I with several tractors and other miscellaneous items for which we have no idea on what to do with them. We are looking for any advice on how we can sell these items to help her father pay for his assisted living. I've taken pictures of all the serial numbers for the tractors. I'm pretty sure they all run. He had a Farmall F-20, IH SM-TA, a cub Lo Boy, and a few others. Can anybody offer any recommendations on where we can begin advertising these items to sell? I've tried contacting the local antique tractor club, the local EDGETA club, and a local farm auction company, and none of them reply or will provide any advice or assistance. My brother-in-law did not leave any information on how or where he purchased these tractors. Please HELP!
