BAD idea. Unfortunately or fortunately, I have learned over many years to stop showing my work until I have finished at least the first draft. If you listen to others at this point, Paul, it won't be entirely your work and you will regret it. Promise. Ask yourself why you want to be a playwright. If it is for money, forget about it. Follow your instinct, work your ass off and then show it to others and/or have a reading with a group of friends.
Here's my provocative opinion: You are either a playwright or you are not.
Do you have any 10 minute or less plays? You might want to post those.
Why are you interested in making this idea into a play? Are you involved with a theater group in your area? Are there other playwrights where you are in Ohio, or is there a playwriting class offered somewhere near you?
If you can find a couple of local colleagues, you might consider forming a small, closed group that gets together every week or two or three to read new pages aloud to each other. The group can then start sharing their reactions and observations about the work with each other.
Cultivating an active, committed small group of artists is a great way to explore new work.
As Edd points out, it can be a bad experience putting work forward that is not yet finished, especially if you are offering it to strangers.
But a group of artists that works together can be a great sounding board and incubator for new work and ideas.
I am currently reading the new book by Pixar founder Ed Catmull - Creativity, Inc.: Overcoming the Unseen Forces That Stand in the Way of True Inspiration. In it he details the creation and continued reimagining of something they call the Brain Trust - which is a sound board for the projects in development and production. You can get a sense of this from some of the articles available thru FastCompany: http://www.fastcompany.com/person/ed-catmull
This page has links to many of the articles about Pixar and how it works. I recommend the book as well.
Anyway - as Edd suggests, start getting your draft on paper. Once there, find some live local people to read it out loud to you.
