So my Questions:
-How do you go about finding individual Slams?
-How do you go about finding features/Venues, so you can travel, and make money at least just to get there and back?
-How do you spread your work here? Is there a section?
I can help assuage your fears because I SAW you win at the Green Mill and you are indeed talented. Here's some answers to your specicif questions:
1) There is a slam map on this site at http://www.poetryslam.com/index.php?option=com_civicrm&task=civicrm/profile/map&map=1&gid=2&reset=1&Itemid=127
It may not be 100% up to date, but it should help you get started. For big regional events, you are right in the middle of the Rustbelt Poetry Slam. So you should check that out, too.
2) That's a tricky question because so much of that is networking. Again, refer to the slam map to get started, start making connections, and get good video/press of your performances. Some venues take unsolicited offers, others want a vetting process, and still more are invite only
3) This is not a great place to post work and get feedback. Other places like www.gotpoetry.com and even facebook (tagging people in notes) are more effective
Good luck and I hope that helps!
