I’m not saying No, more Why?
I think the quality of presentations can only be properly evaluated by professional public speakers.
Movie viewers cannot rate a film by just looking at the script. Likewise, customers cannot rate a presentation by just looking at the slides. If you want a sense of what I can do for you, it is better to browse the videos on my website.
I can assure you, I present in English. I do not use profanities, or any images which may cause offence. And just like a movie goers enjoy the trailer, but don’t ask to see the script, I’m more than happy to share with you both my showreels and examples of me presenting to audiences, but don’t forward my presentation ahead of my arrival!
