I need Mobile App (Android & IOS) for my Phpfox Site

I am looking for a mobile app developer who is familiar with Phpfox and developing mobile app for sites running that script. I need for the mobile app to be clean, smooth and easy to navigate. I need for the profile pic over the cover photo to be in a circle ( this also applies for pages) and the thumbnail pic on posts. I would like the the index page on sign up/login to have a photo in the back ground(I will provide the photo). My site is running on custom theme design (Bootstrap). There should be a like and dislike button in the shape of an heart and a broken heart for dislike. The photos album must be clean and beautiful. Photos in newsfeed must be large and seamless in posts. When clicking on a photo it must enlarge and have pinch capabilities and be able to comment and share. I need copyright and source code after development. I can discus more with potential candidate. I cannot stress that this app must be seamless and easy to use. DO NOT GO OVER MY $300 BUDGET OR YOU WILL BE CONSIDERED!! Here are some features I would like: *Sign In, Sign up and Forgot Password *Push Notifications *News Feed *User Profile *Private Messages *Manage Account, Notifications and Privacy *Members can keep track of newsfeed activities in my community *Members are able to view YouTube videos and play songs *Visit other default modules of PHPFOX easily with the convenient sidebar panel *Allow members to edit title, description of their owned videos/songs *Enable my members to share instant social activities by supporting multiple modules: Friends, Message, Photo, Event, Profile, Video, Music. *Like and comment smoothly on photos, videos and feeds *Share updates, photos and videos *Text and chat speedily via message *Member is able to set one of his photo as profile image or cover photo *Supports core modules of Phpfox like forum, pages, photos etc... *Pages/Group Integration *HQ images in retina display *Smart photo viewer, pinch to zoom *Sync contacts with your phone - invite friends of your users to the site *Third party modules must be able to be supported with app (if needed) *Option to invite other members to an event *Show location of event in map *Show number of attendees of an event *Developer must be able to update app as needed when Phpfox releases newer version
