I think webmasters would be more enthiusiastic if you added a commission option also. Especially for the high roller casino. From a common sense perspective if a player is making an initial $1000 deposit he will be a large spender in the long run. I would rather get paid in commission.
Also, the fact that you’re not listing what software you’re using on the index page of your casinos might be turning away some webmasters.
