I can do that work in 3 days.
I would like you to clarify the following:
You need: ¿development of navigation buttons into the ppt presentation or including websites?
¿you want the music/sound to keep running no matter how many pages you pass?
¿what happen with the pausing tool? ¿is the button that doesnt work or the music is not programmed to it? well, i supposed you wont have those details, but if you need something additional to this, that maybe i forgot from your project brief, please clarify.
Kindly Regards,
Nicole Morel Checo
