if interested in developing for adsense revenue, i would develop, an populate with 300 plus css templates. i think it would garner more money in sale if you had a developed popular site. You would retain your domain, and i would ask for 50% of the adsense income, and 50% of the sale price of the site excluding the domain price. Think about it, i think youd profit better in the end.
try tdnam.com for the domain sales - i have sold like 12 on there and gotten alot of great offers - just get it appraised at godaddy.com and then throw it up in the TDNAM system. you would be amazed at the people that will see it there!!!
