Yup I have around 40-60 trades per month(Daytrader) and I use Charles Schwabb. They charge per trade(No sign-up fee, just min. balance) and their customer service is great, but if you don't even know what to look for in a brokerage firm then there is probably a lot more you need to learn before investing real money...unless you of course enjoy losing it. haha Either way good luck!
