The front staff is poorly trained and unprofessional. Seems like a bunch of high school kids hired to do a job that they're not qualified to do. Numerous billing errors and inconsistent fees presented. Doctor is nice but poor communication with his patients. Not a very good experience.
There are procedures to change the way you look. Your main issue is the prominant lateral orbital rim. As long as you understand you are trying to change the way you look not to correct an aging eyebrow and eyelid there are procedures just for that.
Based on your information if the hump reduction was done too conservatively by simply rasping it down would save money and shorten recovery compare with a revision rhinoplasty.
It is difficult to tell from the picture you posted. However I don't think you need to alter your nostrils too much based on the frontal view of your nose. And if the reduction of nostril is limited you should be able to retain a natural look. With revision rhinoplasty scarring is always a problem and it can make achieving symmetry more difficult.
If money is a big issue I suggest you wait until you feel comfortable financially to undergo surgery to alter your facial feature. You need to find a surgeon who is experienced in fixing your problem and with whom you will be able to get along and most importantly you can trust.
The base of the nose can be reduced by reducing the size of the nostril openings or leave them intact and just change the thickness of the nasal alar. If your nasal base is very wide both should be changed to achieve a more balanced look. There are many different ways to reduce a nostril and it all depends on the shape of the nostril. It is often done in an ethnic nose. Make sure to find a surgeon that has done many of these type of noses.
