audio editing

I am looking for a good audio engineer or sound editor who uses Logic Pro. The person should be experienced or knowledgeable in classical composition, particularly operatic vocals with some accompaniment. I require an old cassette recording of an aria with a female vocalist and piano that was made about 20 years ago on a tape recorder. The project is partly edited in Logic Pro software, but it needs some polishing. Some effects have been added- some pitch corrections and flex pitching but it still needs work done to the instrumentals and some instrumentals added to it in the form of classical woodwinds and strings. So a classical composer is preferred. I would like this to be a collaborative effort so that the edit s I have made can be used and refined by the person I am employing. This is an audio recording in the aiff. format using Logic Pro.
