My daughter is named by Master So. I think he's really so so. He provided only 5 names (which I think really general e.g. 凯晴,卓言,etc.) He also provided 命盘 and I can talk to him personally for further consultation. It costs HKD 2,800.
Now that I am expecting another baby, I plan to consult Master Yeung Tin Ming. Quotated price is HKD 2,500 for 8-10 names, 命盘 and tape recording. I wanna try because of better price and the receptionist was very friendly and nice.
It seems that money is also not so important to them as Master Yeung doesn't expect me to TT or transfer $ to them before providing the service but Master So did.
