What is the most you've charged for a single programming job?
- by David Murdoch
This question/wiki is more aimed at my fellow freelancers rather than companies or groups...but any and all feedback definitely is welcome.
When quoting jobs for anything over $10,000 I always feel uneasy and unsure about the estimate I'm providing (though, I'm not sure why, I know what I'm worth [ I think :-) ] and I charge appropriately. I'm sure there are more (noob) freelancers here on S.O. that feel the same way.
In danger of being voted closed because of its subjective (but factual) nature - the question(s):
What is the largest amount you have charged for a single programming job (not including maintenance, support, or residual income).
What are some of the details of the specific job? (research, q&a, challenges, etc)
What languages did you use to get the job done?
Assuming you bill your work at an hourly rate, what was the rate?
How long did the job actually take you to complete? (from start to deployment, how many weeks, months, years?)
