I tried some of the sites youve mentioned above, some of them seemed free but when you submit your ICO details you will be redirected to another page wherein you will be intructed to pay or an option of performing a certain task but still not sure if your request will be listed.
Did you try Initial Coin List?
We are free and you can also publish a free Press release as a pre-launch promotion. We will be open to the public very shortly and our website will be like no others.
