Help setting up product designer plugin

General information for the website: Graphics
Kind of development: Customization of existing website
Description of requirements/features: I have a plugin on my website called fancy product designer, by codecanyon.
I am struggling to work out how you use it, and if im honest do not have the time.
I need several products creating, that use the product designer, such as t-shirts, hoodies, stickers, mugs, keyrings.
I will also need to know how to use it for future products, so to watch you create one in slow time would be good.
