I can understand your frustration, having seen how the traders in mandis collude against the grower.
I don’t know your location or farm extent, so am not sure of what quantities you are trying to sell. A good crop from an acre of paddy would fetch a net in the range of 15,000 - hopefully you have considered this in working out your economics.
Before you take the big step to uproot the effort of many years, why don’t you post a topic to ask how everyone sells lemons. We can all try forwarding it to farmer whatsapp/facebook groups we are part of to see if there are any more ideas anyone can offer. I see you already tried most avenues but hope you find luck in some unexplored thread.
