新加坡采购需求：配件，钥匙扣

I'm interested in producing custom acrylic keychains and notepads featuring my own designs. Could you please let me know the minimum order quantity (MOQ) for these products? Additionally, I'd like to receive the final products by mid-June. Can you advise on the latest date I should place my order to ensure timely delivery? Looking forward to your prompt response!
