A regular transmission jack with 4 wheels under it and a strap to go around the transmission is handy for the job. A motorcycle jack may work just as well as suggested above, I'm not directly familiar with a motorcycle jack.
If your clutch is slipping are you sure it doesn't just need adjusting? Do you have any free play at the top of the clutch pedal? Free play is where the clutch pedal pushes down easily for maybe an inch, and then pushes harder as the throwout bearing begins to push on the pressure plate. In case you are not familiar with the term.
