budget for a concept art

[ninos]

hello,
i have a question about how much shoud i ask nearly for a concept design work?
it's a concept work of a spaceship design, maybe client will ask 5-10 different styles of it, plus inside- outside, perspective drawings too i guess..
..Client is a production house and they want it for a commercial film.
Should i make a full price for all or for each one a part?
If any concept designer&artist can have an idea please help..
Any information will be helpfull, thanks!

Bill it hourly or as a complete job.
The amount depends on how good you are; not on the job. Professional rates vary according to skill, experience and reputation.
You should have a rate for your work, it has nothing to do with what it is for.
Since you don't know; ask them what the budget is on the concept and either take it or turn it down.

dPaint is right. it depends on the skills.. you can charge according to your skills..
