Let's say you have hired an accountant, attorney, consultant, etc. to work on your business development plans.
As the work proceeds, you ask this person for a referral to someone in another area (e.g., you ask an attorney for an accountant; ask an accountant for an attorney; etc.).
The person then comes back with a few names and says, "I talked to so and so and he's expecting your call."
Do you expect this person to charge you for the time spent "researching" this string of referrals? Or do you expect that because of their network of contacts, they should simply provide the name or names at no charge to you, and expect that their reward for the referral will be the goodwill from the referred-to party?
