For me I feel that consulting a fengshui master is no right or wrong, is whether that master suit you.
Is like consulting a doctor, he maybe good but yet he cannot cure my sickness, but others may not that famous yet he or she can do the job better.
I did consulting a master before, he is famous and old enough, but I still went into a big problem.
My friend recommended another to me. He is only 30+ during that time I engage him for my house fengshui. The problem solve.
Until now I still engaging him as my fengshui consultant.
As conclude, as long you feel that master's skill can work, just go for him right. He may not work well for me, but maybe he work well for others.
Just for sharing.
