First of all, how much trusted are those exchanges to go with. I am not talking about all of those. Have you contacted with them before offering your service? Are they agree or you will contact them later?
Liquid still is on the list when they were already gone.
Exchanges 2 years ago use to have presence in bitcointalk but the new ones today are just not very approachable like the staff of the past. You can't can question them publicly. Now you will have to fill up a form just to ask them. If I have to conduct IEO on the exchange I would rather ask what I need to know thru their support. I suggest this is what you should do instead.
Liquid didn't gone:
https://www.liquid.com/Please, check information and STOP ranking yourself. Exchanges lose their presence because of big pressure, which community used and today bitcointalk community becomes more angier for any of such kind post for 2 reasons:
1) To much fibbers, which thinks that they know everything and dont believe in any new information
2) Getting some status by ranks make you something like godfathers... and all newbies are like dust for you, but i can check your messages story and be assure that 85% of your posts has no interesting info...
