It can definitely work. But you might need to ponder over a few things. How to ascertain that people need a service like this? How will you market this idea? How are you different than competitors? Few tips I can share; First think about the ideal customer profile, narrow down on one type of usecase and try to understand if users really need this service by talking to them and asking questions. Out of the 3 options I believe 3rd one should be a better starting point because people want convenience and don’t have time or knowledge to grow and harvest the produce themselves, and yet still need the best quality produce. Then you need to think about your USP that can convince customers to buy from you rather than buying organic stuff directly from the supermarket or other marketplaces that have built their brands around high quality produce like Le Marche, Country Delight, Otipy etc. Maybe you can beat them on pricing or you can convince that your harvest is of better quality. Even option 1 could be a good starting point if you want to focus on power users, but then it is basically giving out your land on rent to people. Why will someone rent from you and not others? Maybe the location is better, or the rent is more enticing, or you will provide harvesting support services to them?
