That's good to know, there are some good managers in the services section you can find their service thread and you can contact them one by one to get a quote about their service. I hope you would be planning some promotions in your website too, I think signature campaign is not enough.
I think that apart from the signature campaign, it must have some varied advertising on the gambling list site and some on the coinmarketcap site, advertising on many visitor sites will get a lot of interaction to bring in users on gambling sites.
