> Still working hard on a searchable database This would be very valuable for us, because as far as I know there is essentially no systematic way to locate these. We have a product which is meant to be of use to many niche audiences, making them difficult to find. We are very early stage, and are just now getting some initial partners to work with and looking for ways to market the service to initial customers (in the thousands). I would most prefer a marketplace where I would know up front how much it would cost to sponsor a newsletter. Without that, my concern would be friction in dealing with lots of small organizations directly, though we would still be willing to do this at our stage. If payments are happening through the site perhaps you would just take a cut, but alternately if this worked reasonably well and had a fair amount of newsletters for us to find, I would probably pay $10-15/month to use it.
