Hello, ignore the bid price first
I would do this job for you, because it is familiar to me. I have produced various backing tracks for myself and fit original voices to the backing track , or original solos, changing time, pitch etc.
So to be more short.. send me the audio tracks and dialogues, if you want, and I will do a sample of 30 sec for free for you.
If you like the quality , we can discuss the whole job and the payments terms.
See more info about me in my profile and my music page.
I can send you some examples of course.. but the best is always your own sample..
Looking forward to hear from you
