Website like websitewizard.com

We want someone to develop a php + mysql site like http://www.websitewizard.com. We pay to have the php sources. 6 steps 1) choose the address, describe your website, tell us about yourself, login and password 2) set up your web pages 3) edit your webpages 4) theme 5) logo 6) preview You don't need put a lot of themes, but maybe 10 and explain to us how we can put more themes. This software will be tranlated to brazilian portuguese, so the software need be developed in one way to be easy to translate. We will give to our costumers urls like [login to view URL] or the costumer can buy a domain .com. We started a software like that but we doesn't liked the code, it is very confuse. If you want we can provide to you that code. The software need be easy to the costumer change de layout again, only put the login and change. The software doesn't need to create real files, the website can be showed 'on the fly' when people enter in the site's url. The code need be commented.
