I agree with this 100 %. Why he would pay so much money for some random idea here, when with that money he can pay some professionals to do that job.
We all know what those "professionals" deliver during their fixed salary 9 to 5 jobs: crap.
The greatest ideas come from ordinary people like you and me.
Maybe we just think totally different
I would just post my idea along with a disclaimer. You would rather post nothing without an escrow. If a payout is to be made, who has the higher chances?And why shouldn't anyone pay 2500 US$ for an idea. I have seen many people do that before. I have done random 200$ giveaways in the past ... they all went smooth without an escrow.
