Android App Developer

Hello All, I have some ideas for an android app and apple app for mobil phones. I want to start off with Android Apps. I am looking for a seasoned android app developer. I am looking for a developer who codes with performance in mind. I am looking for a developer who has integrity when they build their apps. I am looking for a developer who has a unique style when developing apps. Appearance, Functionality, Performance are very important to me as all APPS are rated by their users. I am looking for a developer who will maintain the apps. I am looking for a developer who will fix issues. I am looking for a developer who wants a long term relationship. I am looking for a developer who isn't shy about sharing their ideas. I am looking for a developer who will test the app out before they send it to me for testing, you must insure that your functionality of the app works. I prefer to only work with Developers who have a history on freelancer and have many ratings. I would like to see your past work/portfolio. I require constant communication via email or any other method. I will publish apps. My first app will be for my current website, I want to see if it would be possible to have the following in an app. 1. I want to create an app that basically will do what my site does. 2. My site is a three member website. 3. My site requires registration for each member. 4. My site notifies people when projects have been posted. 5. Members rate each other. 6. My site has MySql and PHP 7. I will want users to register via this app. 8. Only one member is charged a fee for registration. 9. I want my users to be able to send private messages to each other via this app. 10. One member will have logos of their business, would it be possible for their logo to show up? 11. Currently my site uses zip code db to notify users that match profile criteria and this maintains a 50 mile radius. 12. I want one of our members to be able to search for their needs by inputting a zip code (or using current gps location), and when they enter a keyword and if we have 10 registered providers that are within a 25 to 50 mile radius, 10 profiles will appear to the searcher and they will be able to contact SMS/EMAIL/CALL the users, once services are rendered, we want reminders of the searchers to rate the providers services. so we must tie these to members together somehow... 12. There is more. 13. I will want your input. Thank you.
