Design a product line

We are a plastic distributor and work with manufacturers , we are looking to make a new line of updated Clam-shell boxes, the existing line of products is old-dated and really not up to 2019 standards of design... were looking for someone creative up to date, to design and prepare us 3d files to send to the manufacturer to make samples. the boxes are usually made for cookies, value for the boxes are (8 oz, 16 oz ,20 oz) dimensions do not need to copy the one we have now, hight is around 2-3 inch depending on the oz. ( we can use 1 design and adjust the sizes, so we just need one size design) boxes are clear. (PET metrial) we want 3 different options of design that we can use. the line should be smooth modern, no extra grudges or anything. it should be one size sealed and the other side can be a safety sealing or and strong seal or open proof idea like ripping it up etc more of the boxyer side then round. ( can show a few options.) if you understand the project and feel you can do it or if you have any questions let us know See attached for the old product line we use,
