Vistaprint Packaging Design and Customization Support

I am looking for a professional who can assist me with accurately determining the correct dimensions for custom packaging. The ideal candidate should have experience working with Vistaprint, as I plan to order customized packages through their platform. I have already created a draft of the packaging design but need someone who can finalize the details, ensure all measurements are correct, and handle the practical aspects of the process. The freelancer will be responsible for managing the entire procedure within Vistaprint, including overseeing the order completion.
