You can go the cheap and easy but dangerous way out by getting a regular remote starter kit for automatic transmissions, and then bypass the clutch starter-interrupt switch......
OR, you can buy a remote starter that is engineered SPECIFICALLY for manual transmissions (I know there is one out there but I forget the name, I'm sure you can google it)
It forces you to park the car by parking it in neutral with the key still in the ignition and engine running and hand brake engaged, then while holding the clutch and brake down while it's still in neutral press the remote start button. THEN release the clutch and brake, remove the key, open the door (all the while the engine is still running), close the door, then hit the remote lock button. That locks the doors, sets the alarm, and the remote starter will then kill the engine.
It creates a loop of verification to the remote starter that the car has been parked in neutral, and if that procedure isn't done right, or if you get back into the car and press the clutch pedal again or take off the hand brake, then shut the door, the car will not start if you try to use the remote start.
