Could I have my columella shortened without changing tip angle? Thoughts? Open/closed? (Photo)

I honestly have no idea how a rhinoplasty is performed. (Obviously because I didn't go to medical school.) All I know is that when I place my finger right beneath my columella and push upward, that's how I'd like my nose to look. I do not want the angle changed at all otherwise I'd look like a pig. How can this be achieved? Open/closed - in my case what do you recommend? Expected cost? Can it be done under local? Any additional info would be great. Looking for surgeons in California, thank you.
