Hi,
My name is Khalid I am a pro videographer experienced in shooting case study/testimonial videos for various clients. Based within reach of Oxfordshire I can conduct and shoot an interview covering the general outline as per your document and shoot b-roll clips as well for you with the designer.
I am well equipped with high quality cameras, lens, lighting and audio recording equipment and can handle post production.
My rates are typically from £350 incl. expenses (+ freelancer fees). It would be great to discuss further in chat where I can also provide examples of past work similar in nature. Though I'm UK based I'm close to an airport with direct links to Zurich (and cheap flights) - its possible I can also cover the Zurich designer for you too and happy to discuss.
I look forward to hearing from you.
Kind Regards
Khalid
