Tech pack and Spec sheet

I'm looking for an experienced professional to create tech pack and specification sheet for the apparel products I'm designing. I have a basic concept of the product, but I need help refining it and incorporating design elements. As far as fabrics and manufacturing processes go, I do have some preferences but I'm open to suggestions. The ideal candidate should be highly knowledgeable in creating tech packs as they will be used for production and have a good overview of how things are produced. The tech pack must be detailed and provide comprehensive information about the product and its materials.

Thank you for considering my project!
