Metallic/nonmetal kit packaging design

Design details: Hi, I am looking for a designer to design the following project for me.
let me introduce myself/company so you have a rough idea of what we do and hopefully it helps with design progress.
We are an import/export company in UK, mainly fossils and minerals. bigger piece we use them for furniture/museum pieces, smaller ones we turn them into gift/educational/jewellery products.

So for this project, I need to develop 3 products/artwork (they will be the same series therefore artwork style shouldnt be too different)
They are mineral kits for educational purpose, each kit will contain 15 mineral specimens, one information booklet. a magnifying glass and ceramic streak plate for testing.
The packaging style will be the same as photo attached, paper box with window, specimens will be within a plastic white tray with slots to sit in.
1. metallic mineral
2. nonmetal mineral

i can try my best to tell you the exact specimen in each kit, but I dont think they will be relevant, but if you need them, I will do my best to find out exactly what they are.
box specification :
outer box 19*13.5*4cm
inner window : 16.5*11cm
booklet (folded) : 10.2*15.8cm
target audience : 12+
