Dreaming to work in SG, where to start?

Hi All! So I am working here in the PH in management/finance/consulting field and earning around 70k net gross. Working in SG has been my dream for 2 years, so my questions are:

  1. Any idea what company I can send an application in the same field I'm with now?
  2. What are the expected expenses (in terms of application) I need to know?
  3. Also tips in application process if ever?

Thank you!
