Brian,
Adding a pickup to an acoustic is not very difficult, but the topic is somewhat of a rabbit hole. Unfortunately they all have varying sound characteristics. They can be active (battery) or passive (may need a preamp); Piezo Style (fit under the saddle), Transducer Style (fit under the bridge inside) Coil style (across the sound hole). The best are a combination and utilize an internal mic. Almost all versions require drilling an end pin for the cord. Some require a pre-amp to be cut into the upper bout. Any Luthier or guitar shop can install.
Tony did a pickup review a few years ago. It may be a bit dated, but it is a good primer. It might be on Accoustic Tuesday. Tons of pickup reviews on YouTube as well.
Amps are yet another rabbit hole.
If you just want to record yourself, it can be done with only a phone or simply recording a private Zoom session.
A mic, audio interface and a DAW will do the best job of duplicating your acoustic sound.
Possibly you can avoid all this by starting with an open mic session in someone’s living room.
