I understand if you don't want to post scores publicly, but it might help to have a better idea of how atypical your dd's need are for your community.
On the WISC, what did her profile look like? i.e., did she come out moderately gifted (a FSIQ or GAI around 130) or highly gifted+ (upper 130s into the 150s)? Did she have a lot of spread, which might still indicate a highly gifted child even if the overall number did not? i.e., were her scores all over the place like 18s and 11s or did they all cluster around, say, 13 or 14?
How much time have you spent around other kids her age in your community and/or volunteering in the classroom? This might give you an idea of how much she stands out and how hard you are going to have to advocate/how much of a sacrifice you're going to need to make in terms of looking at different schooling situations.
For instance, while we live in a reasonably educated community with a lot of kids in GT programming and who have GT ids, my oldest has stood out as very, very different from these other kids for most of her schooling. She read dramatically better than most, if not all, of her classmates, used very atypical vocabulary in comparison to others, wrote "better than I do" according to most teachers she's had from 2nd grade on, was unusually intense and had interests and an attention span that made her appear weird and caused her social challenges in elementary, etc. This is one kiddo for whom we've had to make a lot of sacrifices and for whom just getting harder work or subject acceleration in her strongest subject was not good enough.
