Before dropping tons of $, I'd buy some used gear to see if this is something you actually "want" to use.
My rig is crazy simple and serves the purpose just fine for me at home for scratch recordings that are only heard by me and maybe a very good friend or two who isn't an audiophile. Simple Audio Interface (PreSonus AudioBox) and was using Ableton Live, but will likely head the GarageBand or Logic Route on a MacBook Pro. This stuff and a mic or two and you are in business.
See if you really want to use it.
After a year, you'll know if you want to invest more $, and you'd then have a much better idea of what that rig is missing and what your needs are.
I, for instance, felt Ableton Live was overkill for what I personally needed, so I cut bait and sold it off. Before selling, just knowing I had it but wasn't using it was in a weird way a de-motivator to me...
