Professionally cut a song

This song is called Je T'aime by Lara Fabian and is going to be used for the first dance of a wedding. It is slightly too long for a dance choreography and so I want to cut a part of it out (without compromising the quality of the sound or flow of the song!) I want to cut out the part starting with "comme un fou" at around 2:43 and up until around 3:33 where she finishes singing the second "je t'aime". The result will be that the song jumps to the last "comme un fou" as opposed to the second one. Unfortunately the file size is too big for me to attach. I'm referencing the original version of the song which can be downloaded from Amazon music for $0.99. The duration of the song I'm referencing is 4:21.
