As far as i an concern you guys have taken a good step, by ensuring that your platform is listed on Directory and xmr.cludb/exchanges shows that you guys are in for business.
However, I will also advise that you guys should remain transparent, genuine, and trustworthy, build good reputation on the forum because, what will determine the amount of traffic you will generate from Bitcointalk is good reputation.
Furthermore, ensure to run some promotions on Bitcointalk, organize raffles, Bitcoin prediction contest and many more for more visibility. If possible run a signature campaign, just a friendly piece of advice.
