Hi there,
I'm a full-time professional music performer, producer, composer, educator and educational author, sheet music transcriber/arranger/editor/engraver, working mostly with mainstream publishers along with private clients. I've also recently been assisting freelance clients with Garageband production, using native and live instruments (guitar/bass) along with added samples where required.
This is the sort of project I love, and could definitely assist you with. Can I check to see if you're referring to the OSX (desktop Mac) or iOS (iPhone/iPad) version of Garageband?
I'd be able to turn the project around within a week, keeping in contact throughout so we can make adjustments. I've put a 5 day delivery time in the bid, but will certainly be able to beat this deadline.
If you're happy to go ahead then I'd love to hear the raw project you've got so far.
Kind regards,
Alex
