Connectivity is the key to transporting the produce and more so for Agri produce, it being perishable.
The Wholesale markets have formed so they can support the growing areas in the viscinity.
Will need to look, brother. Cant say right away where and how to transport/sell but agree that is the key aspect to handle for realizing the real value of the produce.
Hyderabad should be a great market too!! May need to check there: Dilsukhnagar market (& Mozamjahi?) and I have no much insight.
