Internal staircase

I am keen to understand costs and process to put in some internal stairs in my 2 storey home, the upper level which currently is only accessible via two external staircases. Would be looking for someone to guide on process (building consent etc) although I am happy to do admin if it helps :-) Also have a wall which needs removing (I don't know, but suspect it is load bearing) - again, need guidance on costs, process and capability to complete the works. Can send basic plans if interested, although probablhy prefer a site visit to quote for works.
