The money that the project collects on the ICO should cover all these costs. I think that the team pledged all the necessary expenses for choosing a soft cap.
I do not know about the big fees on the ICO ... now probably it is unrealistic to do now. And what about the soft cap, I think that there is no problem here.
Now its not a problem to assemble a soft cap, but it will be difficult to extend the fees on the market situation, but everything should work
