We are language teachers creating an audio phrasebook for sale. We have a long Garageband file with numerous chapters. We need an expert in Garageband and creating albums or podcasts for download. We have added chapters in the AAC mp4 version, but need help with how this can be downloaded and navigated by customers (online purchase), either through our website or via Mailchimp. We also need the file to be an mp3 too, but with the possibility for chapters for customers to navigate between tracks (this might necessitate creating an album with separate files). Basically, we need someone who really knows their stuff in this area to help us finalise it! We need someone physically able to come to our home in Southbank on a Wednesday or Friday during business hours for a couple of hours to help with this.
