Correction Possible for my Dorsal Hump?

Once removing a hump of that size, usually the nasal bones will need to be narrowed; otherwise a flattop open-roof deformity will result. It is pretty rare to be able to do only a hump removal unless it is very small. Cost of the rhinoplasty is approximately $5700, which includes the surgeon’s fee, anesthesia fee, and operating room.

Your side view indicates the presence of a small osseocartilaginoius hump which could be managed with a reduction. The decision to do more depends on your desires. Generally management of the tip will be completed if you desire a change in the appearance.
Costs will vary tremendously depending on several factors.

Removal of a hump on the bridge of the nose (dorsal hump reduction) can create a dramatic improvement in the profile. It is possible to remove only a hump from the bridge. This can be accomplished by rasping (filing down) the hump through incisions made on the inside of the nose (closed rhinoplasty). Usually, if a hump is removed, the nasal bones must be surgically broken (osteotomies) to narrow the nose and close any gaps created after the hump is removed.
However, in order for the nose to appear natural and attractive, the nose must have certain proportions in terms of its length and its projection. Sometimes, filing down the nose (while improving the hump) can cause the nose to look unnatural or "operated on". This may require some adjustments in the other areas of your nose to keep it proportional and in balance and harmony with your other facial features. These other changes may include decreasing the tip projection or the amount of rotation.
Seek the advice of a surgeon who specializes in rhinoplasty. Many rhinoplasty specialists can show you with computer imaging techniques what your potential result would look like.
