Advice needed for finding end users for my domain

[armstrongdomains]

Hi all, I own the domain "casino25.com". I believe its a highly marketable casino name due to the fact that a huge majority of online gambling sites offer $25 free bets and 25% free stake etc etc.

I've never really tried to find any end users as ive always sold in auctions or forums.

I would just like a little advice on whom to contact and how to go about it to see if I can gather any interest from gambling companies and also any other opinions/ideas.
