Attention to manufacturers of women's modest dresses

I live in Nuremberg, Germany.
I am interested in modest, everyday wear, and modern,
modest dresses suitable for special occasions.
Besides modest dresses, I am also interested in women's everyday wear.

To compete with platforms like Trendyol and Shein in Germany,
I am looking for competitive wholesale prices suitable for the German market.
At the same time, good product quality is very important to me.

If the styles and prices are suitable, I would like to start with a small quantity to test the market.
If everything goes well, I will order larger quantities in the future.

I am attaching some sample images to show the styles I am interested in.
I am looking for dresses similar to these models.
I am looking for engagement dresses and elegant dresses for everyday wear and special occasions.

My main focus is 
Modern, modest fashion dresses suitable for modest wear, elegant everyday wear and special occasions.

Please let me know:
Do you have similar models available?
Wholesale prices
Fabric quality and details
Available sizes
Actual photos and videos of the products
I would like to work with you long-term if the quality and prices are suitable.
Thank you
