Germany importer company request: Bag

I am planning to establish my own fashion brand and would like to have my products manufactured. Could you assist me in finding suitable manufacturers and provide information about the production process and logistics options?

Estimated Quantities:
As we are a new brand, these are only rough estimates. Actual quantities may vary depending on market demand and sales performance:

Per Month: Approximately 500–1,000 pieces across all product categories
Per Year: Estimated 6,000–12,000 pieces.
However, since we are launching soon, I cannot predict exact sales numbers at this point.

Product Details:

Bags: Men’s leather handbags with embossed logo, minimalistic design.
