send bulk messages by whatsapp(Web system only)

Please read the full description of the project before bidding or applying for the position. If you have no experience or no system, do not waste your time and time offering bot programs already ready of other people. I need to send an average of 150 to 250k per day of bulk messages.  I already tested many systems for sending whatsapp in bulk. Some web and other systems that run on windows (desktop). All very good, but as same problem, all are blocked with only 5 or 10 sends. So the whatsapp Bulk messages scheme has to have an algorithm clever enough to prevent this block by whatsapp. How to do this? By proxy, changing the network's I'm connected? By placing fake Ips shipping rules. example: I register 10 numbers of whatsapp (chip) in the system and program to send 10 messages and change number(chip) and so on to avoid blocking. I do not know if this is the best solution. I'm suggesting. Ok, that's it then, below the system description: If you have a web system ready you will be very welcome, if you have already made a similar website will also be welcome. Develop a whatsapp integration API so the system can send messages independently, without the use of placements or without cards. Have a proxi, smart features to keep your account safe and not blocked with anti-lock algorithm by whatsapp. Details: 1. I need to automatically send whatsapp videos, images, text and audio. Bidder needs to tell me how many whatsapp every day or every hour 2. Let me load the contact list via csv or excel 3. report interface shows how many phone numbers have whatsapp, how many whatsapp are successfully sent, how many are not successfully sent, many whatsapp whatsapp, and read received expired. 4. The system must be able to perform predefined automatisms. 5. The site can send text and image messages to whatsapp. In addition, the site can also receive text and image messages from whatsapp. 6) Proxies 7) Easy Sender Payment will only be made after completion and testing on the system.
