Issues with a "Name" actor's management

Well, my production manager is trying to finalize getting Tobias Truvillion for the production. The issues we are having is that they are asking for production credit and wanting us to pay his daily fee. Now what boggles the mind is that some people in the industry think because they never heard of you; they assume you don't know anything about the industry. But they have another "think" coming. There is no way I'm giving him production credit when he has given nothing to the production. He will be paid for his acting but to give him production credit would be foolish especially if they think they will make money off of the film. I'm not giving free money away. When we need to make money, so we can pay those who have helped to fund the production and given their time. So we will see how this issue will unfold. They may not respond to the email that was sent to them. Then we will have to recast the handsome man which shouldn't be a problem. I'm sure there will be someone who would love to play this role.  I will keep you updated.
