Dear Will,
I definitely could shoot these talks for you and edit them to look as good as possible in post. In terms of equipment I have a blackmagic pocket cinema camera plus tripod which can shoot in prores and RAW which are professional codecs. I also have a good range of sound recording equipment if needed.
I have a fair amount of experience shooting expos and documentaries so I am well versed in shooting corporate events and serious talks where needed. If you would like to see a portfolio piece, let me know! I would love to find out more about what type of talks you are doing as this could enable me to feed back some creative ideas if you would like them!
Kind Regards,
Alex
