Design a concept for a roller suitcase (kit bag)

Require high fidelity designs for a roller case, made from a soft shell / canvas material. Looking for a detailed blue print of the case that we can use to start developing prototypes with a manufacturer. The bag will not have a hard shell case, but should feature 'over-sized' wheels and consider usability in the overall construct of the design. There are a number of bags on the market that fill a similar need, so can be useful reference points of the type of product we want to develop. - [login to view URL] - [login to view URL] Requirements of the design: - High quality digital drawings that show the view of the bags outer shell from all relevant angles (happy to start with sketches that then evolve into PSD files ideally) - Concepts for the bags inside, detail on how compartments will work, lid will open etc. - The shape and form of the bag shown - The design on the material on the outside of the bag - Detailed drawings of the key individual components (e.g. handles, wheels etc.) - Consideration for where branding/logo's could be incorporated - Consideration for the colour pallet of the bag as a whole The purpose of this concept design is to take it forwards with a manufacturer, so the level of fidelity and detail should be appropriate to have detailed conversations on construction
