I'm looking to purchase a total of 20 gold medals and 20 silver medals, alongside larger-sized trophies to accompany them. The medals should have a quality finish and be customizable, as we plan to present them during an upcoming event. Please let me know the options available in terms of design, size, and pricing. Additionally, I'm interested in understanding the lead times for production and delivery. If you have any samples or catalogs showcasing what you offer, that would be great. Looking forward to your quick response so we can proceed with the order as soon as possible!
