Hope to find open source ocr app with source code which can read Korean alphabet

Trying to purchase open source ocr app first, then, discuss update data processing process.

- Offline-OCR-capability required.
- When freelancer determined, I will delete this post.
So, as far as you can see this post, it means that you can propose.

If you have open source OCR app,
1) send APK first, so that I can test Korean read capability,
2) and, suggest price
3) Agree on source code price & payment
4) then, discussion on Update task

Please see the attahed apk so that you can recognize required minimum level of OCR capabilty.
Thanks.
