Cool mate. You won't be disappointed over your decision to come down to Singapore as it will make a greater impact for your future. Most of the expats that start at the management level will be seeing themselves peaking up within several years or less to the higher management level.
As for pay check not very sure it could be lucractive in the region of $10K with all expenses, accomodations, cars and other packages provided. (depend too on your company's strength)
