Bag prototyping suggestions

Hi all

I have just completed the finishing touches on a travel bag that I have been working on for a few months now. The bag has some special features that came about from my travel experiences and I wish to create a prototype before heading to kickstarter. I’m looking for professional services that can get me there. The bag will not be made in leather but perhaps waxed canvas or vynil or other material depending on costs, looks etc. Any experiences or suggestions with anyone out there that could help would be would be greatly appreciated. Many Thanks
