If you agree with the pro and don't think another pro should evaluate then I would say get her into another home. It sounds like you are wanting at least a good hunting dog and there is no need settling. Also you can end up with more dogs than you need pretty quick if you are looking at getting another pup.
This is of course based on the fact that you already stated being open to the idea of getting her into anoter home. If you are really close to her, you could always keep her as a pet but the frustration of a dog that just doesn't enjoy the work isn't usually fair to the owner or the dog.
