Chat App for Android

Hi, SIMPLE JOB WHO ARE EXPERIENCE IN THIS FILED My budget is 100$ Open android playstore here for chat apps - [login to view URL] Build something lite-weight & similar. See the points below - almost all are standard features. What I showed you on the desktop - you can take that code and use it in the phone app. What I need for features is: 1. User account create & login 2. Any existing algorithm to search and list users 3. Icon to show online vs offline users 4. User profile with description form & 3 - 5 photos max 5. Profile photo/avataar 6. User name change in profile 7. No chat storage - once closed chat is lost forever 8. Ability to select from hard-drive and send a photo 9. If you can - insert share icon found on news websites - post to social media (not important) 10, Group chat if possible (not important) 10. Every 5 minutes - display a full screen ad on device with a random position Close or Continue button. If the button is clicked the chat resumes. If the ad is clicked user is taken to a website. The Ad is an image (or video?) uploaded from admin section (so the ad can be changed whenever needed). also - queuing of ads from admin - so multiple ads can be uploaded at once - they play every 5 or 10 mins in sequence. Time should also be cms ie. changeable. I would also like you to upload to google playstore Thank u
