Advice?

Hello, I just wanted to see some opinions. 
 

so I have been a nurse for 1yr now and just made the move from med-surg/Tele to the PCU in the small community-based hospital I work at. This new unit does not allow overtime so I went to another(much larger) neighboring hospital to just apply for a per diem position to pickup shifts. 
 

the interview went really well and they offered me a full-time position in their cardiac stepdown unit-which I’d really like to do and advance into the CVICU which my current hospital does not have and they also offered me a $10k sign on bonus. 
 

my current hospital has me tied into a contract for another year because I was in the new grad residency and would have to pay a $5k penalty. I also would feel a little guilty because I literally just finished orientation in the PCU like 2 weeks ago. I also don’t want to burn a bridge with my current company because it is quite large and have facilities all over the country and don’t want to become unemployable with them. 
 

any advice is much appreciated.
