WhatsApp bulk messaging system

Avg Bid (USD)
Project Budget (USD)
$10 - $50

Project Description:
I need a Whatsapp bulk sender to bypass broadcast limit so that I can select unlimited recipients from a text file.
It should allow me to:
- Add sender number ie my number.
- Send Whatsapp messages to a list of my clients, located on a database source (mysql or even a text file).

This is not a spam tool, it is used to communicate to my business partners. I've tried WhatsAPI but sender number gets blocked too fast, making it unusable.

I dont need any particular coding language, as long as it works.

I DO NOT send money 1st. If you want money 1st, don't bid.
I send money only after proof of work or demo is shown.
If your program is based on WhatsAPI and it has already broken ( as in sender number blocks easily), be a decent human (not like a freelancer called bibaswann) and don't try to con my money.

Skills required:
Android, PHP, Python, Software Architecture, XMPP
