Seriously, my advice would be, instead of losing a potentially money making venture, ante up the $7.50, join the '
Premium' section and go over your plans with other professionals without the worry of outsiders or thieves at almost nil. Lay out your drawings and ideas and many here will help you if your idea is indeed worthy of moving onto the next step.
