How To Sell Stamp On Ebay?

Hi Stamp Community,
I have started to sell of my grandfathers extensive stamp collection on ebay, and it's comprehensive enough to just start listing the different stamps. However the real hurdle is promoting and getting some traction on my profile.

I completely understand and respect that I need to have at least 50 post on this site to apply for the selling forum.

I would therefore kindly ask if any could advice me on how I would manage to get my stamps out to a broader audience, or if there is nothing in particular that can be done.

Best Regards Jonas.
