As for removing the old grass once it's been killed, a sod
cutter will
make the removal so much easier that it would still be a
bargain at twice
the (rental) price.

But then, you could just use the sod cutter and skip the
chemicals. Removing the sod will take most of the weed seeds
away, so you will end up with a much more weed free result than
just using chemicals.
