Hello
Is there a company or people that can help ICO development and advising, if yes, is it possible to get some kind of quotation for the work.
Thanks.
There are ICO aganecy that I have seen in here but I am not sure if I'll recommend them since I have no personal experience to any of them.
Anyway, you can browse the service section here:
https://bitcointalk.org/index.php?board=52.0Some have their threads up in there.
Also if you are interested in an ICO engagement firm, try to contact amazix.com
They are a really good team of professional individuals.
