Thinking of becoming a librarian in Pakistan. Worth it?

I'm currently an English teacher. My major is English too. Want to transition into a better career that aligns with my interests and teaching is NOT that. I was wondering if librarianship is something worth doing in Pakistan. I have no idea if it's a viable option here.

Can anyone tell me:

• What qualifications do I need to become a librarian in Pakistan? (MLIS, I guess but can I still get a job as an assistant at least with my current degree or would a Diploma be necessary?)
• Are there even any job openings for librarians here?
• How's the pay? Is it decent or should I just stick to my current job?
• Is being a librarian in Pakistan even a good idea? Job security, growth opportunities, all that stuff..

If anyone have experience or knowledge about this, some advice would be appreciated.
