Well what you want to do is invest in a mutual fund that has low fees and*deposit and*withdraw money electronically. As some have said before try going to vanguard.com or schwab.com*and open an account. I would*strongly recommend that you click around each of their websites and go with the one you personally feel more comfortable with.*Vanguard has low annual fees and no front end or back end sales load, which would otherwise hurt your total return. Schwab however is less restrictive about what you can invest in.
ANOTHER PIECE OF ADVICE:
You should*look to open both a*Roth IRA and*a regular individual account. This way you're not just investing for retirement. Too many brothas take early withdrawals (before 59 years of age) from their retirement accounts and run into penalties that could have been avoided if they had invested some shorter term $$$ also. Obviously some expenses are going to come up between now and when you're 59, both expected and unexpected, so plan accordingly.
