We often have questions about how much you charge this and how how much you charge that as if there is a hard and fast rule about pricing in photography.
I would think it depends on how far you have to travel, how difficult is the job, how demanding is the client, whether pick-up and delivery are required etc. etc. I expect my competitor's price would be different from mine because he can do the job faster, he has lower cost of operation, I'm is more hungry than him etc. etc.
I've just raised a job from a regular client by 30% because he always needs 24 hours delivery and the job requires some PS combo work. I was prepared to lose the job. But he emailed back to agree with it by just "OK. Thanks." I guess he was too lazy or had no time to look for another photographer.
I guess if it's the first job and you want to get the foot in the door it would be probably some kind of a strategy to go low on price but produce much better than the competitors. But I don't have the solution as to how to raise the price later.
