Yes, you can call/email her office and get a quote. I know of a few parents who have done it and they have had very good experiences, strongly recommending the experience.
Maybe you could wait until she is at least 3/3.5 to get a better idea and more useful information from her.
My DD6 for example was not very clearly a level 4 from her lists when she was 2 or 3; it became more obvious as she grew (she was not a child interesting in academics). She is now a DYS. What I am saying is that things get clearer for many kids as they grow older (one of perhaps a few reasons why Dr. Ruf doesn't test young kids).
