Expat getting married

Hello guys! Long story short me and my fiance (Indonesian) met online 2 years ago. We've been living together in Jakarta for the past 4 months now and everything has worked out great and we have decided to step into getting married.
We've been looking for the best options to get married but all churches we ask for information to get married ask for so many stuff (taking classes, be a member for a long period of time...) Is there any way or church that could reduce all this time lines? Or make it more reasonable?

We have took a look into Hong Kong marriage but we havent been able to find the right guidance. Also it was looking expensive. Is this the best option? If so would love to hear how to process was.

Quick note we both are Christian protestant
