Cross platform, OpenCV, Image recognition / retrieve website content

I would like to find someone who can do that kind of app : The user launch the app on mobile device and gets Menu Scene Menu scene is only 1 button to take a shot with camera of mobile device. When the shot is done, I would like to recognize the shot with pics bank i will set. Pics bank is composed of 65000 pics so i don't want that pics be bundled in the app. I would like you to provide me a solution. Matchs are organized by percent of matching on a list. when user click on a item, item scene show informations parsed on html content of website. In fact app will get html content of an url and ll parsed the content to get only pertinent content. About cross platform : I would like it to be crossplatform, but i can accept 2 apps too. About payment : Payment will be provided when it works on my side and i can send the application to the stores.
