You can just ask random people for quests!
I went to a pub and asked this guy if he had any missions for me. He turned to me with a serious look, said and I quote: “I need you to recover an 8GB white Toshiba flash drive I lost around here yesterday. It has some valuable information, but it’s encrypted, so dont go snooping in. If you find it for me. I’ll make it worth your while.”
You can get a bunch of fairly reliable 8GBs cheap from the right places, I use them for boot media or installers or “man it’d be really nice to move a file from here to there without much thought” scenarios
