菲律宾采购需求：灯柱

I'm interested in your tapered lamp posts and would like to know the pricing for two different heights. Specifically, I'm looking for options that are 6 meters and 8 meters tall, with the bottom measuring 6 inches and the top measuring 3 inches, and a thickness of 3.0mm. Could you please provide me with the respective costs for both heights? Additionally, if you have any details on bulk purchase discounts or lead times, that would be great. I'm looking forward to your prompt response.
