Inquiry about Search and Rescue Uniform

I am looking for a manufacturer to produce a custom NEMA Search and Rescue Uniform. The uniform is a two-piece orange set consisting of a long-sleeve multi-pocket tactical jacket and matching cargo trousers. Key specifications include: bright emergency/rescue orange colour, durable polyester/cotton twill or ripstop fabric, multiple utility/cargo pockets, shoulder epaulettes, Velcro identification panels, reinforced stitching, and custom NEMA embroidered or sewn patches on the chest, sleeve and back. Custom sizes from S to 4XL are required, following the attached reference design. Please quote your best FOB or EXW price per complete set for quantities of 10, 50, 100, 250 and 500 sets. Our target price is below US$30 per set, preferably around US$20–25 depending on quantity. I also need details on fabric composition and GSM, MOQ, sample price, sample production time and bulk production time. The NEMA patches will be supplied; production of patches can be discussed.
