New functionalities and maintenance on existing mobile apps - repost

For our existing mobile apps we need changes to be made. The iPhone app: 1 - This app needs to be stable. Now the app just dumps too many times. 2 - There should be an indicator on found profiles on being online or not. When online members should be able to chat (messenger-like) with each other. 3 - Location based search. The member should get a map with active members near him or her when doing a search together with the max distance to his or herself as input. The map shows the members and the searching member is able to click on a profile and see a larger image and some options like 'go to profile' and 'direct contact'. The link 'go to profile' should show the profile of the found member and the link to 'direct contact' should result into a page on which a message can be written (or start a chatsession when the found profile is online). On both options a backlink to the map should be present. 4 - For the add ons under points 2 and 3 pushmessages would be needed in order to inform the member on the events. The events of receiving a message of chatrequest should also be added to the inbox like new messages and digital winks. 5 - The scalability of the shown images is not correct. This should be corrected in all lists and profilepages. 6 - The images should be cached and should not be downloaded from the server time after time when the same page is shown again.

The apps work in a screenscraper way with PhP-serverscripts which connect to the database in order to get the data for the apps. We would like to build a good relationship with a freelance professional or company in order to develop the apps further and further. Besides the dating app of Knuz we also would like to have more apps in the future for our other websites. Based on the development and good relationship we build around this project we could provide more projects.
