Before I call in a plumber for quotes, could someone give me an idea of
how much a PIA it will be to install toilet and sink drains once concrete
floor has been poured (and hardened)? It's about a six foot run to
existing pipes.

It should be done before the concrete. How do you expect to tie in the
drain under solid concrete? I'd consider an ejector toilet rather that
take out the concrete.
