Would you be listing ETH tokens also, because I have not seen token on BTS exchanges.
You mean tokens that exist inside ETH ? The technical process of connecting them with BTS tokens would be pretty challenging (although, quite doable). I believe that's the reason you haven't seen it done yet. If you're talking about ETH itself, I think it's listed over several gateways already.
Also, what is the process to get listed on your exchange, I can recommend your exchange to some project which I am part of the community.
The process is quite straight-forward, we can talk over PM here or exchange e-mails, we're very open in cooperation with other projects.
Just to be clear, however, the projects in question should have like-minded goals. We're all about anonymity and user control; coins we've listed (and planning to list) all have some form of Stealth transactions. If it's something in the similar vein, if it's something that can bring users more control, there's a good chance we can work something out.
