I'm looking to get a quote for a wheelchair. Specifically, I'd like to know about the different models available, their features, and any customization options that you might offer. Additionally, it would be great to understand the pricing structure, including minimum order quantities and bulk purchase discounts if applicable. Could you also provide details on lead times for delivery and any warranty or after-sales support that comes with the wheelchairs? I'm particularly interested in quality and durability, so any information on materials used would be appreciated. Looking forward to your detailed response so I can make an informed decision.
