Build a website based in one I already have -applicaciones.org- and fix many issues about it

Hello, I'd like to build a website that includes Android, iPhone, Blackberry and Windows Phone apps. I already have got one, but I'd like to replicate it to as many languages as possible and modify a few things about it, its now working under Wordpress and its causing many trouble, so I'd prefer to find a way to built it differently -only the new site- and, if possible, to give it a new look. The site is [login to view URL] The crawlers are already working for all 4 stores and of course you could use them, so it should basically be finding a solution about the search queries (I think they might be causing trobule) and redesigning it. Thank you a lot for reading and I expect your offers :)
