Hi and welcome - loving the avatar!
The Any interest in professionally made box sets for Despecialized? thread may be of interest mate.
As well as the An Index Thread (and more) for Case Covers, Disc Labels, and Fan Art… thread - which is likely worth a read through… as it has a fair few differing box sets to suit many tastes, with downloads, ideas, templates, guides, and also some offers of making box sets too, IIRC.
Good luck with it 😃
