This is a really interesting discussion. It's gotten so much attention because you have a really good product. I think you should starting thinking about what kinds of markets you are going to be strongest in and start marketing this as a service to them.. for example people will pay as much as 2.99 for one ringtone. For a custom wall paper or screensaver you could charge $9.99. Keep us up todate with how your doing. Especially with adsense. A lot of times this can be a big indicator of the general value of a site.
I can create an affiliate program for you that will track sales and stats for your affiliates. A lot of people are doing and they are making money. Create some basic designs(like the ones you have). Charge money for the ones that are new or a litle bid more commercial Same of the one before but also custom order. They will be people interested in paying for. Can you place cickable ads?. So I know I will buy the ones I can add my text and it has the opportunity to some how have the clickable option.
Hi, What about Premium SMS services? That way you can charge for each unique video you produce - so if user wishes to use your unique software, he will have to send an SMS first. Or you can offer monthly subscriptions using the same service.
