Hi there,
Thks for the invitation :)
Since you invited me on this project, I will skip the intro about my skills and go directly to the subject.
1 - do you have the 3d model of the card protector? (or it should me designed accordingly with your specs?)
2 - we could discuss about prototyping (i don't have manufacturing capabilities), but this depends on the 3d model of the product (what materials to be used, which technology, etc)
for any more questions, just ask...
regards
bogdan
