If I could sell it for enough to live on...I would give you enough to bathe on (for free).
If we Freepers don't stick together...what do we have?
Check out the competition: Lush, and what they sell at Whole Foods. You won't be able to produce in volume at first, so you'll have to push the whole craft/organic/healthy thingy, too. Consider using organic vegetable oil-- I would think 'local' soy oil might go over well.
Choosing unique scents and adjusting the PH will be your initial big challenges, I think.
You can even try to get a start-up contract from Whole Foods in Chicago/Illinois for a local product.
Good luck, and send me a note if you start selling (I'm in Chicago).
