Website which build simple navigation android application-mobile app builder

I need website which is similar to android app builders. So website who build android apps (in very near future I need it also for Iphone). So there are steps where customer register, fill certain form fields, create app, generate it, preview it and after payment he can download it. This is navigation app builder so beside elements like name, surname, email, phone, etc customer need to mark his object on googl map and to upload 6 photos of his object. All this data need to be collected and generated in one simple app. I have detailed explanation which I will send only serious freelancers who have experience in creating this kind of websites. I WILL TAKE SERIOUS ONLY THOSE FREELANCERS AND OFFERS WHO SEND ME LINKS TO FINISHED SIMILAR PROJECTS. Please, if you can not show me your similar project do not apply. I have complete PDF presentation how this app should work and beside programming website i need design of this website which need to be flat style, i have logo and color scheme, and all elements. Thank you! PS Some similar websites [login to view URL] [login to view URL] [login to view URL] etc just try to type in googl android app builders
