Don't expect any answer from him.
Just looking at his post history, there's no sign of any reply to those threads that he has made to advertise that website and service that he does. That's really a type of poor marketing that there's no answering for such queries that should help him/them gain a book sale.
I also visited their website and tried to ask their customer support about the quotes, but they said that we must send them a 'free consultation' request, but I was not interested in doing that. They should keep all things transparent instead of making their service buyer do the hassle of first reaching them and then knowing the prices. It is not only poor marketing, but a cheap way to advertise a website that itself isn't too active and we don't know who this guy is (is he from the team or just a fanboy/affiliate).
They don’t have enough funds to do marketing in the forum. Neither they are interested in answering queries asked by the visitors.
They just want spoon fed. They want each and every member should buy their service without knowing any details about the service.
Rather if they could have made a good ANN design with all proper information then I could bet that more people have shown interest in the service.
Nevertheless these shill posters won’t stop and better we should ignore them.
And yes don’t pay them a single penny without doing prior investigation of their service.
