Between 400-600/50min, they are generally more formal consultants with certain experience, or foreign training with industry accumulation or study abroad background; 800- 1200/50min is more senior. Generally, you can receive this price with good academic qualifications and clinical experience. Or some individuals float to 1500, especially in cities with relatively high consumption levels.
If you want to choose a consultant, I don't think it's a good idea to look at the price-choosing the expensive one is not necessarily reasonable, and choosing the cheapest one is not necessarily affordable. The important thing is to find the most responsible and serious.
