I'm currently exploring options for sourcing products as a self-employed individual. I'm particularly interested in understanding your offerings, including pricing, minimum order quantities, and any potential discounts for bulk purchases. It would be great to get a detailed overview of your product range, including specifications and lead times for delivery. Additionally, if you have a catalog or samples available, I would love to review them to see which items align with my business needs. Please share any relevant information that could help in making an informed decision about potential collaboration. Looking forward to your timely response!
