Business school and choosing the right path

Objective:
Get into top B-School program in the United States and enter Wall IB/PE after graduation

Background:
International student from a tiny country in South Asia. Completed my undergrad from a non-target in New York.
Spent a summer in Corporate and Investment Banking at a Canadian bank and did half a year of RE development after graduation. Didn't enjoy RE role, decided to move back home which has underdeveloped financial markets.

Currently:
Noticed VCs and growth equity shops opening up so took that as an opportunity to start a corporate advisory business - helping businesses from a corporate finance perspective to raise capital, and investors exit their positions. Since it's a small country, I have an existing network with businesses and institutional investors that I could leverage to create deal flow. There are currently 2-3 ~$1 million deals in the pipeline (first 2 months of operation).

Options:
1. Work for big 4 firm on a finance related but non IB/non advisory role (mostly related to development of financial system in the country)
2. Work for myself and try to close a few deals on small cap raises, maybe some strategic acquisitions
3. Work for an existing local investment bank and help them build their IB business - more on the advisory side (IBs here mostly involve ECM, PWM and asset management only)

Your help would be highly appreciated.

Thanks guys,
