It is recommended to go to a regular hospital. Personally, I suggest you go online and have a look. There are specific case materials for reference. The price is influenced by many factors. If several people in the same area have the same materials, it may be the difference between doctors in different hospitals or the price difference caused by their own situation. Plastic surgery in this area is relatively normal.
My advice is still the same. Finding a professional hospital and a professional doctor is more important than anything else. It is very helpful for your operation to spend some time doing a survey and get to know the doctors in the hospital. Don't believe the false information in advertisements. You may have been cheated.
