I'm looking for some exchange that could generate at least 5K volume per day for a new coin.
I believe you only need to generate trading volume for your new coin and exchange will never work on enforcing/suggesting their customers to trade your coin. It means you need to promote your coin to be attractive enough for traders so that they will get into your coin and may get you the required volume.
I was wondering if you have some ideas on where it would be possible to do a paid coin listing?
Only very few exchanges are having free listing and most others are charging a big amount for listing your coin into their trading platform. This must be the prime income stream for any exchange.
Maybe someone has a list of exchange listing prices or something like that?
You can create your own list by contacting each and every exchange on your preferences. If you check in any exchange, you can find the link for "listing". Just follow it.
