First question, I am doing a pro bono project for a local magazine just to network and get to meet some pretty cool folks, but one of the participants has dropped out. He still wants to buy the images for his use and I am not sure exactly how to handle that. There are about 8 images, mainly 3/4 length portraits. They didn't take too terribly long to produce or process, but the planning stage was a nightmare (he had a difficult schedule) and I had to shoot quickly and think very quickly on the fly. So even though it was a fast session by my standards (30 minutes or so), it was rather stressful and not an easy thing to complete. All that being said, I have now went from expecting nothing to being asked how much I would charge. I am thinking of charging approximately $20 per image. This would cover all my costs plus offer a reasonable amount of profit. I am somewhat confident this would be a good number to offer the client but I do have room to go lower if he baulks. Should I offer to cut my prices slightly? I do believe future work could come from this guy if I treat him fairly. Thoughts? At the end of the day value is only what someone is willing to pay/accept, so I realize it is up to me and him to figure out where we meet. I am just trying to get an idea from you guys what I might be overlooking. Thanks.
Second question. For this pro bono project, do you think it would be a good idea to go ahead and submit an invoice for what I would have charged, and then to create a 'promo discount' line item on the invoice to zero it out? At least then they would have an idea what to expect if they ask me to repeat this process next year (annual feature article). Thoughts on this?
Thanks in advance for your comments. I must say I have learned more from this forum, and from the last 4 months of actually shooting real clients, than I did in the last 8 years of this hobby. Thanks again.
