Is it you or a client that has set the time scales?

2 Weeks is doable for a studio, but not for a single person. Sorry to say there is no way you will get anything completed in 2 weeks.

I agree with the comment stating, work on the environment, get the effects set up and timed and then worry about the character. The character animation alone would take over 2 weeks to get right...

Renogatiate your time scales!!!
