Singer wanted, Heavy Rock, any age

I'm after a singer to work on some songs I've got ready (and loads more to do), ideally something vocally around Godsmack/Metallica/Stone Sour, basically catchy heavy riffs and I suppose elements of 80's Rock.

Not looking for band situation currently as would like at least an albums worth of demos done with the right person first, don't care about age/sex or anything else just a love of music and a voice with some bollocks (if female then metaphorical bollocks are fine)

Please have samples, I have previous recordings where I wrote all the material
