Bill - please reread what I said - after 1 year with the use of all the tools (hubs etc) along with those 360 free sites (and hopefully people still submit to places like DMOZ and other SEs with a made for SE copy of their free sites) starting that second year $1k a week should be average - to break it down to a certain # of sales per free site is not realistic as you will get sales from your "mousetrap" sites, traffic pumps and hubs that you have built along with these free sites (hopefully) although realistically at the one year point you would really only need 2 sales per free site out there if you were still building as after one year you have 360 plus the sites you are building today.
To those making 15-20k a year from submitting free sites I would only say that you could increase your income quite a bit - its not an easy biz and unfortunately that is why so few actually stay in the free site end of it - that compounded with the fear generation that has plagued this industry for the last year has dropped the number of submitters drastically. To me that just means there are even more opportunities out there
