.. building a free website might be the easiest 
way to display such an enormous collection for 
sale. Weebly.com has been pretty good to me so 
far as a host.

Just post the link here with the site hosting 
your images and prices. 
As you can probably tell, some here are already 
eager to see what you've got! LOL!
So your one step ahead. ^_~

Good luck!
