I'm reaching out to you regarding an order for 50 wooden dining chairs. I'm looking for chairs with dimensions of 45x50x90cm, crafted from solid oak with a natural finish. It's essential that the chairs feature upholstered fabric seats in a beige linen material to ensure comfort and style. Could you please provide me with a detailed quotation including the price per unit and total cost? Additionally, I would appreciate information on the packaging specifications for sea shipping, along with any relevant lead times. Please make sure the quote remains valid for at least 30 days. Thank you!
