I don't know the area but one of the benefits of a tester might be guidance in finding friends and school possibilities. Physically sitting in classrooms and observing what goes on is a great help. Testing is key if you are considering an early enterence or starting in 1st grade instead of Kindy. Is homeschooling a possibility? Look for local coops for homeschooling.
I would suggest trying the Handwriting without tears books and materials, in a fun, relaxed way. When dealing with schools on can't expect them to notice and appreciate deep thinking. It is easier for them to notice a kid who needs a personalized path if she is even across the board. Thinking outside the box is very unusual for trainer professionals. You stand a better chance of being 'seen' if you can package her as some understandable variant of what they are familiar with.
It might be more workable to look fir a good and flexible school than for a school that actually fits
