For my birthday, I want to hire a photographer and cameraman, plus developing photos and post-editing. how much is it?

I don't know, thousands of professional ones, tens of thousands of expensive ones and hundreds of them. When is your birthday and how big is the ostentation and extravagance?

Professional is too expensive, amateur you because of poor technology. Just take a picture with a video camera.

If people shoot this, the later equipment is good, the cost is high, and the charge is naturally expensive.
