Well, there are several options, from best to worst:
1. Find the boot CD that came with your Mac.
2. To contact the service, a lot of money you won't lose
3. If you have a friend with a Mac, you can create a bootable CD
and install OS with it
4. Find ISO c MacOS on a torrent, burn to disc and boot from it.
UP. But in the laptop 9 years, it is possible that no service will, for hard rolls.
