Accounting would be your best bet since much of financial advising is how to reduce your tax bill.
Also, get a job as a bartender. Surprisingly enough, I have found that alot of successful brokers/financial advisers had bartending jobs in or just out of college. If you can deal with a bunch of drunks looking for drinks, you can sell alot of stuff.
Take the CFA or the CFP (certified financial planner) which is said to be a little easier than CFA, if you want to advise individuals (retail). If you want to pick stocks at the institutional level then CFA.
As far as majors go BBA is probably a good idea, although, as doschicos said, economics major with finance, stat and math electives is a good idea too, especially for CFA.
