Perfection is unattainable.  You're never going to get something that's perfect, done.  Not with your budget.  Not with your timeframe.  Not so that you can test it to see if that's what people really want.  Perfection is an oasis.

So don't aim for that.  Come up with a good enough that satisfies most of your perfect criteria.  That fits your budget.  That fits your timeframe.  That gets you one step closer to your ultimate goal.  Then ship!
