Shoot client interview/testimonial for sales video

We are coordinating a video for a client to serve as a sales piece for them, featuring a 3 or 4 of their clients from around the country giving testimonials to the value that our client provided. This video will also include some scripted portions, and we will develop those and edit all the footage. But rather than travel to the different locations, we're looking to subcontract a video producer for each city to go to a client's office and film interviewing them with the questions we would provide. We'd anticipate the interview would take no longer than 30 minutes, planning to select a few key quotes from each client, and edit down into a 3-5 minute final video. Looking for a videographer who can help scout a good location to film when on-site, and ensure professional lighting and sound, then send raw footage for us to edit. Depending on travel time, the whole project should take no more than half a day.
