Help on getting Mac back up and running to sell

[twigs64]

I have a Mac Computer 2008. I have decided to sell it. Have followed instructions on how to wipe it clean. I’ve got to the command R , erase the hard drive on Disk utility . Got to reinstall OS X Mavericks. Two options, Macintosh HD or Recovery HD (option Greyed out) if you click on it , it says locked. So I’m guessing it’s Macintosh HD, click on to install , asks for Apple User ID and Password. When I type details in, it comes up This item is temporarily unavailable, please try later. Been trying for the las5 hour, so I am assuming something has gone wrong. Any ideas? Please bear in mind Im no techno expert. So basic instructions would be much appreciated
