By make are we talking gross or net? $1000 a day in sales for a small site like ours is not a huge number at all and certainly won't put a Bentley in the driveway.

Overhead is a huge part of this question. If I were an affiliate making 750 bucks a day from my spare bedroom, I would be a happy guy (well from a living wage standpoint). I don't see how smaller companies could get by on less than 30k per month.
