Hey this sounds interesting and I'd love to talk more about what you're looking for. I've done similar work for some A list celebs including documentary and vlog styled videos for some of the biggest names ie. Selena Gomez, Jared Leto, Idina Menzel, etc.
Not sure if I can provide 4hrs ever single day for a month, but I have a team of freelancers I trust that I believe we can work out a working schedule for you.
