What to answer to emails after you purchase a domain name

Hello XXXXXX

I appreciate your email.

I would like to know if you could help me with the following.
I require a time estimation for production-ready product and estimated cost.

The application should be available via web browser (all browsers should be supported, including Internet Explorer version 6+) - as the customers includes also financial groups, i.e. banks.
It should support all modern frameworks: Angular, React, PHP and jQuery.
It should be fully compatible with all modern libraries like moment.js, node.js, typescript and java.

The application should also be downloadable for Android, iPhone and Blackberry,
with mobile-first and offline-first approach. It has to be both native and work also in web.

The application must have a single code base.
It should be in a single private repository, but some parts of the repository should be open source as we expect a large community.

# The application:
Front end dashboard to control vehicles fleet (autonomous trucks and cars) and provide support.

Select a vehicle
- From a list
- From a db query
- From the live-map
Send a vehicle to a location
- By map
- By pre-made list
- By the workload service

# Technical requirements:
Private cloud with restricted VPN access
High availability and redundancy
Automatic scaling on heavy workloads
AWS Deployment
Google cloud deployments
Azure support

# Front End Specifications
React for the dashboard
Angular for the admin and internal tools
PHP for the animations and widgets. The UX must be very impressive.
It must be pluggable so in the future more features can be added by the community.

# The vehicle should drive autonomously without any drivers

# Roadmap caching service and scraping from other map vendors.
Full API Integration
With Uber
With Drones
With Future API Providers and Map vendors. Must be applied with modern standards.

All vehicles are always located via the live map (Use google maps and also integrate with open-street-maps API)
Vehicles should be able to switch between navigation services, like Waze or Google navigations, or future products.
Detection of errors and bad navigation via the dashboard
Autonomous vehicles should report errors up to 10 seconds after the error happens. GPS resolution should be (maximum) 1.5 square feet.
When an autonomous armoured truck (money transfer, for example) is being attacked or attempt hijacking, it should send immediate report to the backend server, thus sending SMS messages to all registered managers of that route. Two reserved armoured autonomous vehicles should be immediately routed to support the attacked vehicle with the attempt to block the way.
Gas consumption service to detect anomalies
Automatic re-routing to gas stations and sending correct pings and pin-pointing.
A simple machine-learning algorithms should be able to detect the common routes and distances that vehicles of different types exhaust their fuel and report suggestions to improve routes and driving times.
Vehicle malfunctions:
When a technical malfunction happens a vehicle must dispatch all the details to the backend servers, and automatic replacement dispatch will send a static vehicle (with a correct type) to the destination to replace the broken vehicle, as first priority. Immediately after that the service truck and team would be dispatched.
Navigation
World-wide support.

Budget:
Must not exceed 1,500 USD

Delivery:
Up to 3 months for first GA (General Availability)
Up to 6 months for first production-stable release

Thank you.
