How should I send the capital to the Philippines?

By bank transfer from abroad into an account opened for the company in formation, so the bank can issue a certificate of deposit for the SEC filing. Keep the inward remittance records: they are needed to register the investment with the central bank, which matters when you later send profits or capital back out (confirm with your specialist).
