From what I've just seen from your site and without signing up (wife wouldn't be best pleased

) it's not a bad site. Ok, it's table layout and the mark-up is dreadful, but it's pleasing to the eye and clear to navigate. Couldn't see any revenue streams though?
The thing with turnkey sites is that they don't just instantly earn you money. It's simply a quick way to get a site running with possible potential, but you'll need to invest a lot of time (money) to actually start getting users / income from it. With such a competitive market, I'd maybe consider attacking something smaller perhaps?
Going back to actually creating a website I would honestly consider learning the basics rather than using "site builders" / "tools".
I know 123-reg do one, but like I mentioned previously I've never used them.
Another tack you could perhaps take is something like word press or another similar CMS? You simple install the script, which will give you a simple web based editor to maintain the content. Popular ones like word press have a lot of template designs which you can purchase or use the common freebies.
After rambling a bit, I'm off to bed now.
