24’ Nimble Sailboat Built in 1989– help needed in pricing

I am a volunteer with Boy Scouts of America. We have a 24’ Nimble Sailboat built in 1989 that has been stored outdoors for several years. It needs considerable cosmetic attention. It has a YAMAHA 2 cylinder four stroke outboard engine and is on a trailer. A TN Wildlife Resources Certificate indicates the vessel was in water in 2005 and 2006. The sails are present but have not been inspected. Brass accents and a brass galley sink. The boat is in Whitesburg, TN. I have pictures but I’m not sure how to upload them to this site. I am asking for help in pricing the boat. Would anyone suggest a range of pricing? GLAD to share photos if possible. Thank you on behalf of Scouting! KA
