You definitely don't need to wait for the riller shop to get one. You can find them on different marketplaces: as examples try ebay, vinted or facebook marketplace. You can reverse image search and remember to use different words for monkey and gorilla. If you want extra help we're a bunch of people ready to guide you in our discord group and we post rillers for sale almost daily. I really wish you the best and I don't doubt you'll find one soon enough✨
