I agree with both of you. I think the key for me here is to figure out how much the job would pay in a year and divide out like NURB said, but with one change. Because I will be doing this freelance, I also have to figure in taxes and what little overhead I have.
I have read almost every post, in every thread on this site (I don’t sleep well), and there has never been a typical answer. Everyone has talked about it, but they pretty much leave it up to the person asking the question. So, I propose this formula for scrutiny.
First, calculate how long the project will take and what resources it will consume (time, materials, etc).
Second, figure out how much you would make a year (take home) if you were employed doing that job (sketching, 3D modeling, rendering, etc, because, after all these jobs would pay differently as a specialty), add taxes were appropriate, and divide by appropriate numbers for the length of the project.
Third, add in a premium if there are extenuating circumstances (ie, time constraints, exclusivity, contract limitations, etc.) that would prevent you from taking on additional work while working for the client.
Finally, take these numbers and see if they seem realistic. Sometimes a reevaluation is necessary to bring the numbers in line. IF they seem good, send a quote and if the client wants to know how you came to that number, and you feel like sharing, break it down for them.
This may seem like common sense to some, but I had to think about it for a while before I came to this basic formula.
What do you think?
