Where to sell Premium ".co" domains QUICK !?

Tweet

Does anyone know where can i sell some premium ".co" domains FAST? I know i could sell them in many places at auctions but i cannot wait for 30-90 days in a free auction and i cannot pay for their fees at this moment. :( I have some surprises like googlestore[dot]com and yahooshop[dot]com ... and other search engines domains :) Many thanks!
