Publicising a raffle/competition

I'm not even sure this belongs in this section but here goes anyway...

Hi, I'm looking for any suggestions to get some publicity for a fund raising raffle that I have coming up.
I am a keen cribbage player and play on who have agreed to hold the event. Plan is to sell raffle tickets on-line at $5 a ticket. (American based site but money will go to parkinsons uk) Purchase of 2 tickets gets you entry in to 6 mini tournaments with the winners getting extra tickets in to the draw. There is one prize only - a unique cribbage compendium which I designed and built. It is made from solid elm and features three variants of the game(2 of which (Kings and crash cribbage)are copyrighted and reproduced with permission) details to be posted on shortly. The distributors of Kings cribbage in UK have posted in their newsletter but I would like to get to any players in the UK to give them a chance at this - and to raise more cash!

any ideas or help??
