Write a salesdeck in English

We're a Belgian Based Company specialized in Business Model Innovation. We would like to create a new storyline for our existing (Dutch language) sales deck (that we present to prospects during meetings and pitch moments) And, make use of storytelling and copywriting skills to improve our text and wordings. This new storyline for the pitch/sales deck should be in English Language. (Graphics and such are done by our local partner so it is really the storytelling and copywriting we're hiring for.)
