Sorry but no. I don't care if the founders are prepared to dedicate the rest of their lives to it (assuming it is founders and not founder), after all you could dedicate your life to making a better mousetrap but for me that would be worth $0.

The guy is basically asking how much his time is worth without giving his qualifications for all you know he's flipping burgers at McD's.

My brother in law came up with an idea for a better garbage can, not immediately obvious and not in production anywhere, after some 'research'.

What is it worth?

For me it's worth $0. He has no background in manufacturing, sales, marketing or design, he does not have anybody that would dedicate his life to it, and he's not prepared to mortgage his house and let go of his day-job to pursue it. So it won't be going anywhere.

I don't see this guy making any statements about what he will bring to the table either other than the idea, not even implicit ones, no statements about commitment or anything.

So, more info is needed. Both about the idea and the OP (track record would help but likely none or he wouldn't be asking the question).

No realistic valuation ever rested on this little info.

Sure 'angel' investments fall in to a certain range, say 0 to 10% of the stock for 0 to $1M. But that's like saying the sun will be shining tomorrow, that's not an answer to the question.
