Lawyer bills $300 for case review, including one hour to discuss the review. Dropped off paperwork and a check for $300 . . .

. . . Lawyer called us and said she is in receipt of the paperwork and would review the case for merit, and said if she takes the case she needs a $5,000 retainer and $300/hr thereafter. Secretary called to tell us she is making some phone calls to the school district''s attorney to assess initial reactions to our requests for out-of-district placement and would let us know their reply. We heard nothing for a few days and called to follow up. Secretary said she could have lawyer call us but wanted to help us avoid running up a big bill. I was surprised to hear of additional billing as we had hardly exceeded the hour of time included in the $300 review fee. I asked about charges to date and was told that the lawyers calls to the school district''s attorney are being billed at $300/hr. We have no written agreement and were never told that billing had started. They seem sneaky to me. What can I do?
