Nope, e-mail service would be cheaper...in any case, but why? People can get a free email up to gigabyte with maximum security. Even with a search engine, it is not going to beat some big guys like Google, MSN, is it? I don't mean to tell you that this stuff isn't possible, but maybe If you think deeply in this, you can find some or a few unique ideas, something that users will need and use.
If you drop the Search, eMail, idea..and drop the entire idea of portal-like. You could think of something like ICANN registrar, I like the idea, its not easy though, you need a lot of hands, developers, designers, partners, and on top of this -- a good capital. The return would be good, very good. That's different to search engines, because the domain market is already competitive, we don't buy domains from one registrar, so another registrar won't hurt the industry, it would be a good benefit ~ unlike search engines, the top search engines already known, and they are popular enough..MSN, Google, etc..but look at domain registrars, there is not a leader, so why not yours could be one of the leading registrars.
So what I'm saying ~ try to avoid the idea of portal-like sites. And you may disagree with me.
And no ~ don't quit so early..
