Mastercard, Visa: Q1 Earnings May Be Fine, But Guidance Will Be Weak

I have about $ 5000 that I was considering putting into a term account but think I will have better return by investing in Visa. I’m learning more about investments and VISA sounds good to me. Is this something I can do on my own through E-trade or ING or should I work with a company to get some stock in VISA? Please advise.
