Hi all- I've got my first commercial client after starting my LLC. The client is a major car dealership in my area, and he's requesting photos of three of his dealerships. The images are to be used in their commercial marketing. I've got my commercial license ready to go, and legally speaking everything else is in place. My question for the professionals out there is related to pricing models. With commercial clients like this, what's an fair rate for such a project? Do you pros charge more of a flat rate, or a cost per final image? Any advice would be helpful. Also, please know that my photography LLC is more of a side-business, as I hold full time employment elsewhere. Hence my 'noob' type question here. Thanks for looking.
