MacBook Pro 2009 OS X install problems
Coincidentally I had this exact problem on the same type of macbook yesterday.
As Tetsujin correctly states the mac is too old for internet recovery, and since the drive is probably empty, there is no recovery partition aswell
If you have the original grey install discs that came with the mac, you can boot from those by holding the "c" key during startup.
If you don't have them, you'll need an other mac and an external hdd case.
You can than connect the ssd via usb to the working mac, and then use internet recovery on that mac to install osx on the usb connected ssd.
