Whatsapp application to return information on sending short text messages

Avg Bid (USD)
Project Budget (USD)
$250 - $750

Project Description:
We would like to publicize certain short message codes to our clients on Whatsapp e.g 'GET HELP PARIS CLINICS', 'GET DURBAN WEATHER', etc

We therefore need help developing script(s) and website to enable us to:
1. Configure these different short text messages and the action they will perform
2. These messages will be linked to a back-end MySQL database that contains this information to be relayed back to a client on whatsapp
3. receive these short text messages when sent by a whatsapp client/number, process it back-end and return the requested for information to the client/number that sent in the message
4. Log each request received and each successful/unsuccessful return of information request in the backend MySQL database with time (and location/IP) stamps
5. Create a subscription service such that after a certain number of requests, the system will prompt the sender to subscribe to continue receiving the service

Please note:
- Actions to be performed by short texts should be configurable back-end on the fly
- Subscription option should also be configurable
- If one has a demo that can do this, please share so that we avoid any unnecessary delays
- An additional script to send bulk text and pictures messages to a list of Whatsapp number will be an added advantage for consideration
- website should HTML or WordPress based and assistance will be required to transfer it to a host once tests are passed
