Dear Jen and Allysia!
Thank you for you reply. Yes, I'm not alone, I gathered a small team supporting and helping me to realize my dream. That's why I so value your opinion - to draw some inspiration, because I'm working, not so much for profit, but for the idea to do something nice. That is not industrial production, (that's why the price is rather high), but if I believe that it is in demand somewhere else, I will do everything for further work!
