Confidence when pitching yourself does not always come naturally, especially when you do not have a long track record to point to. One thing that helps is focusing on what you can do rather than what you have not done yet. Writing clear, honest proposals that explain your approach and show that you understand the client's needs tends to work better than trying to oversell yourself. Practicing by writing pitches even when you are not applying anywhere also sharpens the skill. What helped you feel more confident when you were first putting yourself out there?
