Doing friends Senior Portrait

[RmSchrom]

A friend of mine asked me to shoot her senior pics. I've never done a real photo shoot, and the only equipment I actually have is the camera and a diffuser. It will most likely be shot outside, but what equipment would I need that could be homemade? I don't have the money to buy a lot of equipment, and I'm doing this as a favor for her.
Help!

Here are a few examples of portraits that I have done...

i cant view your facebook portraits but a good place to start is a reflector. you can buy a piece of white foam board for cheap at craft stores. under $10. just get a big piece of foam board and use it to light them properly.

I'm not her friend and I could see the pics. The first one is the only one that's any good. The other two are just snapshots. There's thousands of examples of good senior pictures online. Look on here and Flickr.
