巴西采购需求：手术室设备，包括手术灯、手术台和医用吊塔

I'm interested in your ceiling-mounted LED dual dome medical operating light with wall control. Could you please provide me with the pricing and any additional costs involved for delivery to São Paulo? Also, it would be great to know about the warranty and service support options available should there be any issues after installation. Additionally, if the light requires repairs in the future, can you provide details on who would assist with fixing it? Are there any authorized service centers in São Paulo, or would I need to contact you directly for support? Your guidance on these matters would be much appreciated.
