Bulk WhatsApp messenging

Hi,

I need a competent programmer to build a simple website/ android app (to interface with an existing API) that allows the users to type in their messages and get those messages sent out to a list of similar users who opt in to receive these information.

The API is open sourced, could be found here -> [url removed, login to view]

This website will:

1) Allow me to register my mobile phone number and get WhatsApp to call back with activation code.

2) Allow me to upload my phone numbers via CSV and to verify and show the numbers with WhatsApp accounts.

3) Allow me to select all or individual contacts to send my message.

4) If possible, allow attachment of at least 1 picture.

It will not be set with any broadcast restrictions, but probably limit its maximum sending per hour.

Let me know how you intend to acheive this project. Thanks!
