If you are launching your ICO and need buyers of your tokens, write to me in the mail ( dmitrii.zigman @ gmail.com ). I can help you sell tokens. No prepayment required.
Will you be able to sell those ICO coins which are not on exchanges yet ? I do not think that is possible for you. And for those coins which are already on the exchanges, we do not need your service, because people can themselves sell their tokens and coins on exchanges.
