I would prefer that instead of partnership with someone, invest few money, get web sites developed, and run by your own. Because partners, are always pain in the hell. If you are looking to make money, you need to invest money, that is simple.
But if you want to get the websites developed at lowest rates, you can hit me up by pm. I can do it.
So you get a domain, than you expect someone to come in. develope, run and make a profit which they give to you...
Why would said person not simply register their own domain? Your asking for a profit for spending $10.99 on godaddy..
