The next Round of the ICANN new gTLD program is coming and - just like it was the case in the previous Round - it will probably be very difficult to know what to do for any new comer to the program: where to start from? Who to talk to? What level of service? What price? Etc...
A list of Service Provider
There are not so many service providers
worldwide but those I know - and some I have already worked with - can be very good at what they do. This list of providers will probably help many to learn more from the ICANN new gTLD program and help for consultations.
Small Reminder: do not tell the string you plan to apply for unless you have chosen your provider. Signing a NDA does not mean that you have to tell your string with the people you plan to talk to about your project.
I will promote and update that list on social networks and LinkedIn.
