You need to break down the project.
How long will it take to shoot this?
How many people on your crew?
What are their day rates?
What’s your day rate?
What’s your day rate for all of the equipment?
What’s your mark-up going to be?
How long will the editing take?
What’s you edit rate per hour or day? The same for authoring, graphics, etc.
What’s your client’s budget?
What do want to walk away with at the end? Profit?
hat are production rates in your area, based on someone with your level of experience
The problem we often have is exactly this. A client contacts us with how much does it cost to produce a 2 hour DVD ? It all depends on what goes into the project, and what your rates and profit margin are.
