Actually, I’m not sure you should see a financial planner. My understanding is that their fees can be several hundred dollars, which is likely more than their advice will net you. Your situation is fairly simple, in that you don’t have any real tax concerns (being poor) and just want to put your money somewhere it can grow.
Go to the library or bookstore and start reading personal finance books. There aren’t actually that many options, and the books I’ve read have laid things out fairly simply. Here’s my incredibly uneducated summary:
money market account: slightly higher interest than a savings account but not FDIC insured, i.e. it can go down in value or go away if they institution goes under
CDs: slightly higher interest than a savings account, but you can’t access your money for a fixed period of time. You can set up overlapping CDs, though, so that a fraction of your money is available at any given time.
stocks: you buy shares and gamble that they will be worth more at some later point than when you bought it. You should probably know a lot about the company and industry to make knowledgeable choices.
mutual funds: a much better way to buy stocks, in my opinion. The fund buys a mix of stocks from many different companies, reducing the risk if one company tanks. Different funds have different annual fees, so shop around. Index funds have a predetermined mix of stocks, e.g. corresponding to the Dow Jones index or S&P 500, so there’s less management and the fees are lower. These are usually a decent bet if you don’t know what to buy.
There’s also bonds, which I know fuck-all about, but which I’ve heard can be more stable than stocks, or tend to go up when stocks go down, or something. I repeat: I know fuck-all about bonds.
Good luck. If all else fails, get the money in twenties and roll around in it.
