Let me start by saying I get it, sometimes the ‘magic’ of a guitar gets ruined by a well intentioned guitar tech.

That said what you are describing is a complete re-finishing job, and possibly a gutting the guitar down to a husk and replacing all the parts. The paint will easily cost upwards of 1-2k, and swapping out everything with decent parts could cost $500 - $1,000.

The ‘wife’ in the green text said she spent $200, for that price you aren’t getting much, fresh strings, a setup, and possibly a spot level and crown for any high frets. A few minor tweaks, that in theory could be undone.
