MP3 Song File Editing

I need a talented sound editor who can professionally handle my request to adjust an mp3 song file. Your tasks will - Trimming and cutting certain sections - Rearranging sections - Extending the song's length by an additional 1-2 minutes -I'd like the violin part that goes for about 17-34 seconds to be doubled up (played back to back) in a way that flows naturally. Then double the song length from there. Ideal candidates should have a good ear for music, proficiency in using audio editing software and experience in working with similar audio editing projects. Flexibility, creativity and attention to detail are paramount for this job. Your main goal is to smooth out the edges of the song without compromising its overall quality.
