@Lisa Dermer ballpark depends on number of shot locations and days and the number of cameras. 3-camera one day, multiple interviews runs about $2500.
You can get the archive footage edited down in the $750 range.
I agree with @Angie Albright – community access channel staffers are great, but it will take time (and you have to take their orientation). But it opens up a long term relationship (particularly in a local market). We are exploring this relationship however we haven't had time to send a team over to orientation and then create the video storyboard required prior to shooting.
Student videographers can work too, however if an intern, 120 hours only takes you so far and usually the ramping up time is worth paying an experienced professional to get it done (with limited oversight).
Remember you get what you pay for.
