A business idea

I have a mostly planned cannabusiness idea. I think its pretty cool. A few close members in the canna biz have been pretty excited about it.
My prob is i can only provide a idea. Im looking for a partnership. Would be willing to offer 50/50 you would carry the risk financially. im just the brains.
Not sure how to discuss this without possibly losing my idea to a more successful company with money to spend.
Any help or thoughts would be amazing. Thank for the support. GN is changing the Canna community. Im PROUD to be here! STAY GREEN
