Design for a kids toiletry/lunch bag

Hello, We would like to create a kids toiletry/lunch bag, externally looking like a kids lunch bag and internally customisable to suit different uses and products. We're looking for help in getting a prototype designed, and in finding a suitable manufacturer able to manufacture the prototype, and subsequently, a small volume of bags. We have some ideas and we can provide some amateur drawings of the concept and features we want included. We're looking for a professional designer who could provide the following: (a) Assist in updating design drawings to include technical features; (b) Provide 2D/3D Concept Ideation & Direction; (c) Provide 2D/3D Concept and Specifications; (d) Locate a manufacturer who will (i) make a prototype, (ii) provide patterns, and (iii) provide competitive pricing; and (e) Work with such manufacturer to get the prototype completed. The concept and features of the bag are to be discussed once the Industrial/Product Designer is chosen. All rights in the work produced is to be owned by us and we expect to be given all materials produced. If this is the kind of project you'd be interested in and available to work on, please contact me and provide me with a fixed quote. Many thanks
