Inquiry about Custom Couple Blanket

I am looking for a custom couple blanket with dual comfort zones. Specifications: total size 240x220 cm, left side as weighted blanket with compartments (approx. 6-7 kg), right side as normal blanket, and a middle strip of 15-20 cm without weight for comfortable transition. Materials: soft cotton, washable, with possible different colors per side. Features: compartments on the weighted side to prevent shifting, and a hidden zipper connection system for attaching or separating the blankets. I need 5 samples for testing before larger production. Please provide price, delivery time, and minimum order quantity.
