video chatting app with matching contact

I wish to create a real-time business marketplace app where people can network, solicit business or find expertise. The components of the app are: User Profile User profiles registered via Facebook. To pull name, age and last 3 or 4 profile pictures via Facebook. User location obtained via phone GPS. Business interests entered into user profile e.g. aviation, healthcare, insurance Matching Users are presented with the distance of up to 200km to match with other users Users are presented with a screen that shows ‘online’ users within the specified distance and at least one matching interest. Video A user can request a video chat with matched users. The other user will be able to see this request, the profile and be able to accept video chat or decline. **I want to be able to set a customisable time limit on video chat and also have a timer displayed whilst video chat is in session. After video, they are presented with a Yes or No option. If two users choose ‘yes’, they will be able to continue messaging via a ‘Let’s do business’ section. If anyone chooses ‘no’, they will go back to the ‘matching’ screen. Let’s do business This section is a text chat area that consists of users that you have previously had a video chat with and where you both clicked ‘Yes’ at post feedback screen. Users can send messages at any time to each other in this section.
