Customised demin cardholder and bags

The products are for school project. The type of cardholder is shown in the second picture, but the material will change into demin. The size of the bag is shown in the first image. It has a zipper near the top of the bag. If you agree to take this work, we will purchase 10 for both cardholders and bags at this time and will reolder them as our project goes on. Please tell me how much it will cost for cardholders and bags respectively if we provide all the materials you need.
