I'm interested in exploring options for different types of custom medals. Specifically, I'm looking for various designs that can cater to different occasions, such as awards, sports events, and corporate recognitions. It would be great to know what materials you offer and if there are any customization options available for both the design and engraving. I'm particularly keen on understanding your minimum order quantities and production timelines as well. Additionally, it would be beneficial to see any catalog or examples of past projects you've completed. I'm also curious about the pricing structure and whether you provide samples before placing a bulk order. Any information regarding the various finishes and additional features you can offer would be appreciated. Let's work together to create something unique and impactful!
