Chestnuts as a food crop business

Hi we are a family that is lucky enough to live in an orchard of chestnuts in Victoria, Australia. We are starting to sell some of them around town and I’m wondering if anyone has any tips on selling chestnuts you could possibly share. Do you think it’s too late in the season in Australia to start selling them ? Are there any issues with storage or insects for example that we should look out for ? Any advise that anyone could possibly offer would be so appreciated 🌿🌳🌰🐿️🌿🌳
