美国采购需求：鞋拔，短鞋拔，木鞋拔

I'm reaching out to get a detailed quote for an order of 500 units of a specific model I'm interested in. Could you please provide the pricing information, including any bulk discounts you may offer? Additionally, I would like to know your typical turnaround time for an order of this size, as well as your production capabilities. I'm also considering adding custom logo engraving to these items. Could you let me know if this is possible and how much it would cost per unit? Your prompt response will be greatly appreciated as I am eager to move forward with this order. Thank you!
