Is this a good idea?
Should I write a proposal for it?
Devil, meet the deep blue sea!
If I say yes, this sounds great, write a proposal and then pass on the proposal, I would feel like I've led you on. My guess is you would too, and start shopping for flaming bags of dog poop.
If I say no, this sounds like shite (flaming), you go away feeling like crap and maybe I missed something good. Or worse, you don't write the proposal that another agent would have jumped on it with all four feet.
That's why you have to write the proposal before you ask me (or any agent) to offer any kind of assessment.
Plus, ideas are a dime a dozen.
Even good ones.
It's the execution that matters.
