Baby sleep and back to work 😥

I can’t believe in 2 weeks I am going back to work! I need some advice for my 8 week old! Right now we have a bedtime routine that starts around 7:30. By 8:30 she is in her bassinet and drowsy. However she fights sleep the ENTIRE time. Constantly spitting out her paci and crying. Around 11, I feed her and swaddle her again and she continues to fight sleep until 1:00 a.m. She consistently falls asleep around 1 and wakes up at 6! She will then sleep again until 9 a.m. How can I move her schedule up? If this continues I will only get about 4 hours of sleep before work :/
