Your third option is a regular garden hose. Bring the hose in through a door or window (have it turned off, of course), put it down the pipe as far as it will go, add towels and rags around the drain to keep water from backing up, and then get a partner to turn it on and off in short spurts. The pressure from the water might work bathtub to loosen the clog.

Before choosing any plumbers in your area be sure you pick a contractor that has experience with similar projects as yours.
