CGI design for sci-fi film

I'm need to create a couple of sequences for the sci-fi project to be used in presentations to investors. The sequences are as follows:

1. Two spaceships rushing through space towards, and past the viewer.
2. A sequence showing one of the ship's exploding
3. 1 min sequence inside the ship (a corridor or one of the rooms) after it has been ravaged by the explosion to be used as green screen background.

As I said, this is work to be done to attract potential investors, so very little money available at this stage, but if I find the right person and the project goes ahead, there will be more and better work coming. Please only reply if you are enthusiastic about being part of the project rather than trying to make money out of it -- I know we all have to work, so I'll be upfront saying that in the short term you'll find better income somewhere else.

Thank you!

Please note, this is a re-posting of the previous job with changed criteria (cost per job vs per hour -- sorry I'm new to PPH.)
