Robust Application

I am looking to develop an app that has FEATURES similar to Uber. (this is NOT a taxi service and we are not trying to replicate, we only have features of this for our unique idea) Programming that allows 1st party to alert they are leaving their home within 30 minutes. Programming that allows 2nd party to see this alert. Request the 1st party individual. 1st party can accept or decline their selection. • Programming that allows the 3rd party (Us) to collect a percentage of the amount paid for this service at the end of the ride. Programming that allows both parties to chat after they are matched (texting or maybe calling the person (identifying information and phone number must be collected). • Push Notifications for both parties Later in App Development, the following features. GPS technology to locate individuals (1st party) who are asking for a service • Programming that allows 2nd party to respond and be lead to the 1st party • Programming that allows the 3rd party (Us) to collect a percentage of the amount paid for this service (we are a third party) The below programming languages are most applicable. Front end iOS native Objective C or Swift Android Native: Java Scala (future forward language) Hybrid app C#: xaramix Phone gap (java script) Backend: server data storage (what is best option cost ratio) SQL PHP (best bet, very common, more so than python) Python Combo Ruby (don't want to double dip that, hard to find that) C# or C++ Median that goes in between them Baas systems: (back end system that is prepaid) Push Notifications Note** ONLY SERIOUS PROGRAMMER NEED APPLY. We are looking for some people (or individual) with real skill that will get the job done fast but efficiently.
