What can you advice someone who wants to do a liver transplantation?

Look for a center. Look for the best liver transplant center. Make certain you are not drinking alcohol. If you smoke stop! If you can get listed in multiple regions, do it. Keep your nutrition up with high quality protein and if you can do some exercise do it to keep active. Make sure you have a reliable support system lined up for when you come home.
Have to more clear. Your question sounds like that you want to be a transplantation surgeon, hope you want advice to get a liver transplantation. If that is the case through your physician you have to enroll into your regional program, and meet the criteria like end stage liver disease. Early localized malignancy etc. If qualified team can initiate immediately if family member donates or wait in the list for donor.
