Since you're new I'm gonna give you some pointers on how to ask questions to get proper answers.
Start by giving a short description of your current situation. Include details about the rep you own or are interested in, such as the factory, brand, model, or any other specific feature. Which movement is included here.
Clearly state what you're looking for or trying to achieve. If you're seeking a particular dial, specify the type, model, custom or straight aftermarket etc.
Are you planning to handle the task yourself or are you hiring someone. Maybe they have their own favorite places to buy from.
Mention Your Budget. There are differences between Raffles and Viet dials if you're looking for vintage Rolex for instance.
The straight answer to your question here is on the forum. You just have to search for it. If you need specific answers you need to ask specific questions.
