Clean installing El Capitan on 2009 MBP

I cannot clean install MAC OSX 10.11 on my 2009 Mac Book Pro.

I need to repurpose this older MBP for someone else here.

I have tried numerous times and a few different ways.

• Installed starting from 10.6 and kept installing each subsequent system until I reached 10.10 but when I tried 10.11 no luck.
• tried from an external drive that had the 10.11 installer

tried using DiskMaker X Pro

• Tried form the recovery partition, re-downloading the OS directly. It looked this was working because it took a while for it to download and install. No luck.
• I was able to clone my own 10.11 volume from my MacPro to this MBP but of course that was not the final result I was intending seeing I need a clean/new system.

I have provided a screen shot of the message that comes up everytime.

I tried all of these attempts more than once with the same result.

Any info would be much appreciated. I have been fighting with this on/off for a couple of months now and I am completely baffled with why this will not work.
