Its not as straightforward as you think. Exchanges are now flooded with requests, and *if* you hear from them, I am hearing it is ~6 months out to get a slot, and if you announce the date, they drop you. Its all very weird, but my guess is they are trying to discern more what ICOs are good, bad and ugly and trying to filter to avoid a dotcom bust like opinion of blockchain businesses. It makes sense, and puts the onus on the marketing and business plan to be rock solid.
The CEO of Binance wrote a post underscoring this recently:

What about the small exchanges like kukoin or ether delta , Would be awsome to meet somebody that handled this.
