Are you posting a job offer?
You may want to re-post your question in an appropriate forum. Perhaps Indie Film and Documentary would be a better place. Also check out the business forum.
Regarding your question – You may want to figure out what gear and equipment is required to do the job and what the daily rental rate for that gear is (or would be if you had to rent it). Add that to the day rate of each person on the team.
I believe this is the figure you are looking for. It is a starting point for you to negotiate with. Of course this doesn’t factor in expenses such as food, travel, permits, tape/media, etc.
If you don’t know the day rate of the team members find out what they would like to get paid and how low they can afford to go on that rate. This is the kind of information you need to have in order to negotiate a contract with your client. Also, find out the approximate number of days that production is expected to take. Many crew members will lower their day rate if they know they will have a large number of days of work lined up.
