Review my startup: Weddingjojo.com
replicatorblog: I agree the monthly fee is not where you want to upsell. I would break it down by feature. A bare bones site is $15/flat. If you want a premium theme, another $15 if you want to tweak colors, $5 customized emails $5/1000. More of a virtual goods approach rather than the hosted solution route.Also might be some interesting alternate monetization routes. You could set up an Amazon affiliate link so YOU get the bonus for anyone who buys. Have people pay a fee to turn off Adwords on their page (ala Ning) Set up an invitation designer tool and actually help people get their cards printed. That takes time to set up but could be very lucrative.
