The problem with trying to do something like this yourself is that you will make a mess of it, guaranteed. You're also going to need to invest heavily in tools and hardware just to do the work.

I have no issues in people attempting their own wiring and the only way to learn about things is to try them yourself, but in this case I can absolutely guarantee that if you've never had any wiring experience you will seriously struggle to do this. The number of dodgy wiring jobs I see as part of my day job still amazes me.

I can't recall anybody who's ever punched down a frame on their first attempt (and I've both seen and taught people by letting them try first after some basic guidance) who's done what I'd describe as even an adequate job. Most people untwist and expose too much cable, and that will lead to performance issues.

There are times when paying a couple of hundred dollars to get somebody to finish some work that should have been done by the person who started the job is actually worth it.
