保加利亚采购需求：4线别墅套件

I'm looking for a quote for a 4 Wire Villa Kit. Could you please provide the pricing details and estimated delivery timeline to Bulgaria? It would be great to also get any information on bulk order discounts or different shipping options if available. Additionally, if there are any specific features or variations of the kit that I should consider, please let me know. Understanding the lead time will help us plan ahead, so your prompt response would be appreciated. Thanks!
