2 to 3 concept designs (product design / industrial design) based on my requirements

Industry: Sports and Fitness
Design details: I have an outline requirement and brief for a product, but I'll be asking you to sign and return (by scanned email) a simple Non-Disclosure agreements (NDA) prior to sharing all the details. The product is in the category of sporting goods and is a bag/accessory. I will explain everything once we agree to work together.

I'm looking for some skill in idea generation, as well as design & illustration skills. I do not have a pre-conception of how/what the final design will look like, only what functions is must serve. You will have some creative freedom. I will be looking for either two concepts (if they're rich in lots of views and visuals) or 3 concepts if they're less fully described. I'm happy with pen/pencil sketches or CAD renders depending on your preference.

The purpose of the concepts is to be included in a business plan. For that reason, they can be CONCEPTS (you won't need to prove that they can be built).

I would hope that if the business case is accepted, you will be able to do further work to elaborate the chosen concept as it moves towards manufacture.
Target audience: Industrial Designers, Product Desginers
Messages to communicate through the design: A new concept of accessory
Modern, simple (think Nike/Joseph Josepth)
Ideas for the visual style: See attached images
Things to avoid: Low quality visuals. Lack of inspiration
Where the design will be used: Business Case.
Extra notes: Have included some images to show the sort of concept sketches I'm looking for.
