Help Assembling Network Cable

Hello Neighbors, I have a small networking need and before I go purchasing a plug crimper and a bunch of cable and connectors I’ll probably never use, I figured I’d check with all of you! Perhaps there’s a cable guru out there in the HP world... Specifically, I’m looking for two ~3ft shielded twisted pair cables with RJ11 plugs (could use CAT5 or CAT6, as long as they’re shielded and have at least 4 twisted pairs), each wired in opposite order from end to end. These are very tough to find but very easy to make and I just don’t wanna buy a crimper and connectors and cable I’ll never use the rest of. I’ll happily compensate anyone who’s able to help. Thanks!
