Write an iPhone application

I have the app basics all ready made by another freelancer but they didn't do a every good job with all the features i wanted. I want to be clear on the features. First the app must be able to grab information from multiple social networks and music apps such ass facebook, twitter, pandora or spotify. The reason why this needs to connect to those apps is because I want the app to grab information like interest like movies, hashtags, and recent songs they listen [login to view URL] app is similar to hot or not where it shows people near your location and shows the amount of interest two people have in common. It is NOT a dating app but a app to help communicate socially. The previous developer did not do the location correctly, I want the app to search for people around a very close radius say like a bar,club etc. The user can also change the distance. I also want the user to be able to bump another user, no not the app bump but more of a like button where it sends them a message saying they want to meet or talk. Lastly, I need a way for bands, venues, artist etc. to be able to create a page for just their events. And the app would have a page just for events near the users and it would display all the needed information. List of updates: [login to view URL] interests, recent songs and hashtags from social networks and music apps. So it can be easy for users just to connect instead of manually entering them. 2. Cleaner and better location side of the app so it can find "compatible" users. [login to view URL] which is a like button. 4. Event pages, where artists etc can post some events. that list from nearest and date of event. These are very simple updates. With the api for grabbing the information and making everything look cleaner and easier for the user. I want this done Fast and cheap. I would do it myself but I don't have the time. I have all the current files and I can send them right away.
