How to solve the problem using NS?

Question

Neural networks

Hello. There is a task - it is necessary to solve it) I know that there are resources and competitions on Google (sort of), but other than this resource, I personally do not know anything. The task came from behind a hillock, there is payment. Not big and not small.
The task itself: There is a wholesale warehouse of flowers. He has flowers that are sold during the seasons of spring....autumn. There are buyers. there is cash/clearing payment. It is necessary to predict the FUTURE, i.e. try to predict WHAT flowers buyers will buy in 3-6 months? Those. The wholesaler SEES that buyers are not only buying spring goods in the spring, but also shopping for summer and autumn flowers. And when summer comes, the wholesaler is not ready) And buyers buy spring goods - they also buy summer and autumn goods, then they leave for themselves and probe the demand for summer or autumn goods. then they are returned, and the wholesaler cannot provide them. this is the essence) Is it generally solvable? If YES, then you need to somehow decide)
