Breast implants/lift for woman with naturally large HH breasts? (Photo)

Without examining you I cant be entirely sure but it sounds like what you would need to achieve those results is a vertical pattern lift (a.k.a the lollipop lift). This would correct the sagging and provide excellent projection of the breasts giving the perky appearance you desire. An implant could certainly be added if you wanted to increase the size of your breast in addition to lifting them. The only way to know for sure is to book a consultation with a board-certified plastic surgeon near you. Best of luck! 

You seem to have ample breast volume, and would not need implants but rather a breast lift (also called a mastopexy) to achieve a better shape.

With naturally very large breasts, it would generally not be advisable
to add implants on top of the weight from your already HH breasts, especially
if you’re wanting the breasts to appear higher. This would only add to
the weight of the breast tissue. If you want the breasts to be higher,
then a breast lift or mastopexy would be the primary procedure to
consider. Hopefully this is helpful to you. Best of luck!
