How can I become Alternative Model?

Becca wrote to us asking for advice on becoming Alternative model. She's 16, she lives in USA, and she's very photogenic.

I think the best place to start is internet, do some research on alternative models, read the interviews - models often tell about the beginnings - maybe it was in an alternative models' agency, maybe they were scouted, or maybe they simply contacted alternative photographer and started their own portfolio.
There's also plenty of online guides on becoming alternative model, here's just one:

Perhaps you have got experience of your own, please share your tips, maybe you can help Becca and others on their way to becoming  new alternative model?
