Hi all. I have just done some animal models for a client and have supplied my Tiff files ready for print. The cost for these 10 images was £120 each but now the client is asking for the models as part of the cost. This wasn't said during the commission of the job so there was no negotiation to include extra cost for the models. Each model is taking 10 hours to do, this is the time it has taken to supply the tif images but what cost should I ask for if he wants the models also?
Thanks.
