Where can I hire a digger

I don't know about diggers, but after living in houses with dirt gardens and a "green fingered" missus, I admire your desire to remove the lot and replace it with solid concrete, My ideal "garden" is 50m2 of six inch thick concrete slab - painted green, with little drops of white and yellow for "flowers".  No mowing. No scrabbling the dog poo- clean it with a hose pipe. ........ ~Ar ... yup.
