I think I need bigger boobs. Do you think I should get a tit job done? And what size would fit me the most?

You should strive for the body you want, not what others want. If bigger boobs better match how you see yourself, then absolutely go for it. But do it for you, not us. It's like trans people having work done to better match how they feel inside; it's not really about others, it's how about they feel when they look in a mirror and what they see matches their mental model. Do what you feel is right.
