You will be able to find affiliates here, but if you're willing you can also check other means of promotions on the forum; bitcointalk is very effective for building a community that will help brand your casino. This doesn't being the direct results as affiliate marketing does, but it has good long term positive effects.
You can start by having an ANN and building traffic around the features your casino offers that will attract new players.
Having an announcement thread here could help them better, rather than relying on affiliate marketing as a strategy for promoting their business on this platform. They forget that this platform is not like other platforms, where people can just promote any kind of stuff and do away with it.
I am happy that you, as a reputable person, are also saying it because you are a manager and you know better what it entails and what OP is presenting here. So it would be better if OP looks into it and does the needful, because I do not think affiliate marketing works properly here on this platform, but rather a promotional campaign would go a long way to give the casino visibility here, as there are a million and one registered members who frequent the casinos registered here on this platform to play games with them.
One of the reasons why members frequent casinos here is because of the casino's official presence on this platform, so they will have the confidence that whatever challenges they have, their representative would be able to attend to them, and with that effect, they build trust and reputation over time. So if this casino could do the same, they could achieve their goal of getting traffic from this platform, not just through affiliate marketing.
