Sedo? GoDaddy? Also, I'm looking for parked domains, earning at least $50 a month...PM me if you'd like to sell...
Also, avoid Godaddy at all costs, they make you pay a monthly charge to park your domains, that's a complete joke!
From my experience, Godaddy is good for buying domains. That's it. Hosting, parking, development, just about anything, can be better done somewhere else... Again, that's just what I have found.
Does anyone make $100+ a month from Parked domains? If so could you share how many (approx) you own, how long it took you to acquire them and your primary source of domains?
