Hi,
my name is Mauro and I'm a BA in Audio Production (SAE Institute) and certified Avid Pro Tools operator; as Audio Editor, Designer & Engineer I may help you out with your project.
I could design this laugh at the required length and provide it at high quality in a very quick time, delivering it via Dropbox both here and if required to an email address.
Please get in touch for a quick start and pro result.
Best regards,
Mauro
