I have had very good success in getting still pix with providers. I think that a video 'success' rate would be nearly as high - but I am not wanting to do that as the 'distraction' for me would be even greater than the pix. Taking the pics is distracting to some degree and can affect my 'performance' (it happens with an older gent like me).
What's the secret of my success?
Build a good rep -- Communicate beforehand, get mutual, keep your end of the agreement. Be sensitive to the provider's concerns over privacy. Learn to crop, blur and data-scrub.
In my experience, most providers want me to write a review. So I do.
In the review, be accurate for your colleagues, but be respectful of the provider as well and let her see and approve of the images that you plan to post. Tell her that she is welcome to use the images in her showcase, ads, etc
Maintain it. -- Do what you said that you would do.... and (very important), don't do that which you said that you wouldn't do.
Practice it. -- Patiently follow a successful algorithm.
Repeat. -- After a while, the girls will contact you!
