In addition to South Carolina as mentioned above, Tennessee offers a Finance major with International Business Concentration. It looks like merit aid for these stats would be $7500 against a total COA of $52k, so maybe a bit over budget (though their personal and transportation allowances are higher than many others, so billed costs might come in under $40k).
Ole Miss would be comfortably under budget with $10k auto-merit. They offer a Finance major but not sure about the extent of the international business possibilities.
