If you are going to go for a shy girl, you are going to have to make the first move - and be prepared ahead of time with topics and things to talk about the first couple times you take her out (or else you risk those awkward silences). I see you are 19, so the best place to meet girls would be in school - if you're not going to school right now, sign up for classes, preferably classes where the class is involved (think like art classes, etc.). You can also get involved in groups that involve things that interest you, so at least you will have an "icebreaker" to approach women with.
I will say, though, that you shouldn't close the door on outgoing girls. I used to be a little on the shy side, until I started dating a very outgoing woman (she would strike up a conversation with strangers while walking down the street), and we got along great - I didn't need to do much talking, because she would always have something to say. It was actually easier than trying to date someone shy because I didn't constantly feel the pressure of having to come up with conversation topics. It also made me a little more outgoing. But, to each their own.
Either way, good luck
By chance, I just noticed your post in the new people's forum. Here's an idea - see if that female friend of yours has any friends she will set you up with. When I was about 18, I was in a similar situation with a girl that I thought was out of my league - I had her set me up with a friend of hers - her friend and I didn't work out, but somewhere along the line the girl I thought was out of my league developed a thing for me (admittedly, I was young and stupid and didn't pick up on the most obvious signs - here's the story if you're interested
