It's true that not all new projects can afford top exchanges but we have few exchanges that aren't that costly for IEO like binance or okex, here are some exchanges that are still good and less costly
1. Hoo.exchange
2. Probit exchange
3. Upbit
4. Bithumb
These exchanges still have good results of past IEO projects

Probit is one off top choice of the up and coming project to host for their IEO so I won't get disagree with your choice but I don't really about the other exchanges you mentioned but recently OIKOs has successfully concluded their IEO in hoo, but that is the first time I have heard about, while in bithumb there are some projects didn't really turned out well as expected.
