"I realize I need excellent images but I don't have the budget for this. Can you offer a discount?"
That's a common question.
Perhaps you could consider fewer images. If you are just getting started with a portfolio keep in mind a few great looking images will do more for your brand than twenty not so great images.
There is an option of cost sharing. For example, if additional parties such as a vendor, architect, or contractor would benefit from use of the images a split fee can be arranged that brings the total cost down for all parties.
What if I have a unique request? Please inquire.
