Need Help w/ music for movie

Hey Everyone,

   Well I've been working on a few projects and I need a little help. I need to find someone that knows how to edit or loop music. I found the perfect theme song for my movie script and no matter how I try to do it, I just can't seem to figure out how to take out the vocals in the song and I still suck trying to get a continues play of the beginning of the song. I've tried using a few different programs that has been suggested to me. And for some reason it's just not working out for me. So I was wondering if anyone out there knows how to do this kind of music editing?

 I need at least a ten minute loop of the first 2 minutes of the song song below. Plus a 12 minute and 30 second looped version of the song with the vocals removed.

   Ozzy Ozbourne: Zombie Stomp  (Length of song is 6 minutes and 15 seconds)

   I've tried to do this myself with a music editing program a friend gave me, I just haven't been able to get it to the point of sounding close to what i want. If anyone can help me with this, I have no problems with placing your name on the film credits as the Music Coordinator and music Editor. Any help will be excepted.   

   Yes I've been trying to write a movie script and so far it's become a real challenge, but it's coming along nicely. Just about finished with the script. I took my first script that I wrote and the new script I was writing and combined the two. It's turned out pretty good. Yes it's a Zombie flick, how would it look if I wrote a vampire script and my main genre in the horror films is zombies...(LOL)

   It's about two groups of survivors during a Zombie Outbreak and the conflict of two different groups wanting the same things, but have different means of reaching their goals and what kind of conflict may happen between to leaders bucking to control both groups.

   That's all I'm saying for now. Because it could change or could go into a whole new direction. But the soundtrack is set to use only two songs, Zombie Stomp by Ozzy Ozbourne and I stand Alone by GodSmack.  Which I stand alone will be the song I use to close out the movie. But as for Zombie Stomp, it will be used completely throughout the movie.

   But getting the soundtracks the way I need them so I can here how they sound is a complete pain in the ass. That's why I'm asking for some help from anyone who knows how to edit music. A ten minute loop of the first 2 minutes of Zombie Stomp, as close to seemless as possible, and a 13 minute loop version of the whole song with vocals removed will let me know where to place everything within the movie. I mean I have it all in my head, just trying to get it where I can hear it is something else. So If you know how to do this, please feel free to contact me to discuss the idea. 

Thanks
