Hi,
As a professional Prezi designer I can help you with your presentation. I am working with Prezi for over 2 years and I give workshops and training to larger companies about how to use it. Besides that I also make custom-made Prezi's. You can check my portfolio her: [login to view URL] but a lot of Prezi's are made for private pitches and are not public.
I have space the coming days and I'm available via skype and e-mail so if you need to get this done quick and professionally, I can be of help.
Kind regards,
Kris Vermaas
