Ajaxload.info similar website

The web-site has to have functionality the same as www.ajaxload.info. The web-site will need a generator for the preloaders and an interface for fast creation of new preloaders. PM me with details of how the admin will create the preloaders in your vision. Something like the screenshot of a preloader generator form. No software development algorithms - just the vision of preloaders management. Any PMs excluding the details of the administrative side will be ignored. The preference will be given to PHP developers (no matter PHP4 or PHP5), though .NET developers are also welcome. The winner will be the bidder who provides the easiest way for generating the preloaders.
