Film brief interviews to supply video clips to include in another video

I need to supply several short video clips (30 secs - 3 mins) mostly of 'talking heads' being interviewed to a third party. They are to be incorporated into another video - the 3rd party will do the production and editing, so there is probably very little editing involved, mostly camera work. You will need to supply the equipment, including a decent microphone so the voice quality is good. I assume this requires you to supply the camera, lighting and a separate mike (but happy to be advised otherwise, this isn't my forte). I'll arrange the locations, interviews, script/questions and organise things. I will arrange to suit us both - eg, all on same day if possible, or on 2 different days. Timing is flexible, deadline is 4 months away, so sometime in the next couple of months is fine - again, I can fit in with you (and the interview subjects of course). Deliver: 7-8 'talking heads' clips in 4-5 different Melbourne locations, and perhaps some very short video of workplace/s (10-30 secs each). Am happy to pay per hour (if we agree on a reasonable cap) or a fixed price.
