Create a sketch for approval then 3D image of new duffle bag design - repost

Hello Creative People! I am the owner of a brand new men's accessory company, and we are very excited about a new duffle bag we will be launching soon, that has some ground breaking features. Until now we have been using our limited design skills to sketch up diagrams for our factory in china, which they have quoted from. However before we get the first sample made up we need a designer THAT SPEAKS PERFECT ENGLISH to work with us to create the following: 1 x hand drawn illustration of the exterior of bag - Possibly 2 amends or until we are happy to move to 3D 1 x hand drawn illustration of the inside of bag - Possibly 2 amends or until we are happy to move to 3D 1 x 3d exterior of bag illustration (based on signed off hand drawn illustration & with detailed measurements / material guide e.t.c) 1 x 3d inside of bag illustration (based on signed off hand drawn illustration & with detailed measurements / material guide e.t.c) We will provide you with: 1. sketches of bag 2. measurements / material needed 3. creative brief 'for additions to exterior' 4. written description of the bag and its unique function 5. on going support / communication via email / phone /skype We will shortly have the brand created by another designer which will be sent over as part of the brief for this project. We have a good idea what we want the bag to look like and exactly how we want it to function inside. However we would ideally like a designer who is a little experienced in fashion design, and can suggest then add some creative touches we may not have thought of. It is not a necessity to have this experience however, but you would need to be able to work to creative brief and ideally suggest / design some simple touches or additions that could give our bag the edge over the competition. As mentioned we may decide to just go with our existing design for the exterior of the bag, but very keen to see if a fresh set of eyes could come up with anything we like. Any questions do let me know
