I'd like to offer share farming

Hi there

We have an exotic tropical fruit orchard covering about 4 acres with over 100 varieties of exotic fruit trees. These include black sapotes, jaboticabas, yellow mangosteens, grumichamas, Macadamias, several types of mango trees, jackfruit and ketmebillas. Wesell the fruit locally but no longer have the time to maintain teh orchard. pcik and deliver the fruit.  It is only a small business but could be easily built up by someone with more time on their hands. We would like to offer a share farmer the fuit  in exchange for caring for the orchard.  The arrangment would suit a local retired farmer/ orchardist, an aspiring horticulturalist or a couple who love fruit trees who would like to spend time on a farm.

Would anyone know of where to post such an offer or know of anyone who might be ingerested?  Your advice would be appreciated.
