From what I recall, Dick and Jane live closer to the west coast than to the east coast. So yeah, going to Dr Pousti would probably be a lot more convenient than going to Dr Revis in Florida. I would say to check each of them out, if travel is an option.
Also check out Dr Foster, get a consult with him.
I could possibly suggest others, but those would be my top 3 choices. Getting the consults with each will afford the opportunity to go with the "warm fuzzies", those nebulous qualities which are about as far as one can get from the logical left brain.

But the right brain can absolutely contribute to this; pay attention to "gut feel".
Now for the conundrum of sizing.
I would recommend mocking up the additional 1500cc using:
- dry rice in an old stocking
- water in a sufficiently large but smooshy balloon
- Play-Doh or similar (use cling film to keep clothing from getting ruined)
For any of the above: measure out 1500cc for each breast. Stuff into appropriate container, and smoosh around the breast (below the nipple, wrapping like a demi-cup bra).
A larger bra might help with the mock-up.
Whatever the current bra size, figure on roughly 250cc per additional cupsize. So if the current bra uses H-cups, then start looking for N-cups.
