I have been asked to help my girlfriend clear and level her garden (about 10
metres square)

It is all at different levels and will need the earth moved around to get it
level. So my thinking is that I would get a rotovator to break it all up,
rake it etc, then roll it flat for turf

You are likely to have a few inches of good topsoil on top of a depth of
poorer soil. Make sure that in all your levelling you don't simply strip
all the topsoil off the higher areas. Not a problem if she just wants a
large patio, but it will be a problem since she wants grass - the grass
will grow better on the once-low deep top soil areas, and she'll end up
with a patchily coloured lawn with bits of it particularly liable to
browning through drought in the summer.
