it will take time to gain trust from the users here. if you will continue addressing even small issues from here on, i guess in time they will trust you..
also if you have funds for promotion of your site, you can always have the sig campaign managed by reputable campaign managers here...also, you need to review about the personal information that a player needs to submit..i think thats too much considering there are a lot of known casinos here that dont require kyc..
