I'm not against this but to give you an idea ICO investments are not gender specific products you can promote, they are cryptocurrencies and can be used or invest by any gender. ICOs are not like cars, magazines, or even perfumes in which you need a girl to get their attention to. They are more interested in what the ICO has to offer and for me hot models in the ads would just add more skepticism towards the project rather than that attention you are expecting.

And for your pricing..... Don't you think a thousand dollars (or more) per model is a little bit expensive just for the project itself? I'll surely understand this price if you will be the ones running their marketing as well but by the looks of it seems like it's not even included.
