Bookmark sites

I'd like to have the promotions for one website about gambling. I think that it is ok to do the promotion with Guestbook Sites. Do you have one list ? and one list about gambling ? I don't want that you do the submissions in the website where you can do the submission ( or review ) of the my website one time. [ I want to know where you do the submission ] I can have the possibility to write articles so the promotion can be better. The payment can to be for submission or for every new player that I have [ for this the payment is done after that I receie the player ] [ I am open to new way of promotion you can suggest to me ].
