It sounds like you need me to visit your market ( or my market... It only takes one super user per market and I assure you I am almost always there), film everything and then feed that into your website. I like the idea, but it's not complex for my fanatical farmers market mind. It only has two geographic regions and okay 1 is only hours driving from me, but I would be more likely to use it if it was my own region.
Also it has a picture of an avocado and no data about avocados.
And don't get me started on the market availability between the first hour and the last hour because if I keep losing all the caviar limes to the restaurant buying the whole batch I'm going to start camping at 6am.
Some things I hunt for: Concord grapes, pomegranate, caviar limes, raspberries, mara des bois strawberries, amaranth and all types of kale.
ETA: the early girl tomatoes I recall as end of May or June, probably mid June for you. Too late now I think. Those little orange oblong ones are good though and my favorite breed of tomato is Japanese tomatoes. They have almost 100 percent availability at my market too because they have a specialist grower who uses green houses.
