有沒有人可以幫我改一改文法&改通順一點??(英文好的請進)

It is important that I should provide the best French-style service in the right way for those customers who are senior officials or meeting groups form the leading organizations. Furthermore, one thing I was concerned more about is that I did not have service practice at SHMS as I performed before because of my direct admission to the third year program. It seems to someone that these tasks may be difficult.
