Just to quantify it, most "restomods" start at $100K USD.
Decades ago I had a buddy that did something similar with a VW Bug that he did "on the cheap" doing almost all the work himself and things like paint through connections he had, I never talked price on it but it was at least $30K I'd bet and probably more like in the $50Ks, and took around a decade.
