Write and produce a zombie numetal song

Id like a soundtrack writen and produced for an upcoming zombie project. The theme i have for this song is for the strong to survive, i.e. survivors of the zombie apocalypse to be strong when up against almost impossible odds. The lyrics will reflect mainly the survival aspect but could include the zombies, and be in the style of a numetal song. This requires a male singer or mainly male singer with female backing (the other zombie song i had done was all female).
There are several songs that inspired me for this, but the two id like you to look at are:
breaking benjamin - blow me away
only the strong - flaw
If you have any questions then ill answer them, but as im working away with no net access i can only do so on the weekends.
