I would write the unit files exactly as you did.

Easy to check: if you execute the command in a shell does amandad
background itself? If yes type should be forking, else Type=simple
(the default) is fine.
What you can try is to remove the "-" in front of the ExecStart
command. systemd will then no longer ignore an exit status != 0 and
will mark the services as failed. Maybe you can get more info about
those services (exit status, listed PIDs,...)

One more thing to check: if you use a very recent version of systemd
(afair v35 and up)  try adding StandardInput=socket and
StandardOutput=socket to the service file.
