Contract growers information required

I require information about contract growers. I have 200 hectares of land that’s available to use with 3 phase electrity. I plead with anyone who’s responsible for contract growers to please contact me, I’ve been to Olifantsfontein offices but unfortunately they don’t let anyone in, I was given the managers contact details last year and early this year I found he no longer with them and they gave me another one that I’ve been constantly trying contact with no luck. Thank you.
