It is unusual to need a behaviorist for a 10 week old puppy. What types of issues are you having that you think could benefit from private training at this age, particularly help from a behaviorist?
We may be able to suggest some things like books, videos and other basically free resources to start with compared to the expenses of private consultations.
Also may be able to give ideas/suggestions on tactics to avoid in training for whatever issues you are seeing.
