Looking for rare minor and junior cards

[Crw21]

Hi, all.

This may be a longshot, but I started a unique hockey card collection during the pandemic, and I can't find the below cards. Given these aren't great players who've played many/any pro games, I'm hoping they're sitting in someone's closet. I'm willing to buy these essentially common cards and would love if anyone can find them, and I'd even buy the sets if they're sealed. I've searched eBay, Armchair Sports and Centre Ice Collectibles without any luck.

Alternatively, if anyone has any advice on where to find these, I'd greatly appreciate it. Thanks in advance!
