Dear carlito944,
I'm Ikhsan an iOS developer since 2010 from Indonesia, but currently studying at Leeds. You have a UK profile so I think we won't have an issue around timezones. For more information about my past works, you can check my online accounts;

I have worked for a similar project making an interactive storytelling app for Danish artists (https://www.freelancer.com/projects/2699432.html).
If you don't mind, you can share your keynote prior to this project. I can provide you a sample work (maybe to animate the first 2 pages) for free. You can try and check the quality of the sample code first, If it fits you then we can discuss your project further.
Many Thanks,
Ikhsan
