Looking for maker in Berlin for gear for new sport

My name is Juan, and I invented a new sport called Toche. I am looking for a maker to produce some of the gear needed to play the sport. I have come up with some prototypes made of PVC that we have tested for years and now want to do something proper. the design is simple and recycled plastic would be perfect.

The work at hand will require refining the design and making the products.
