Bulk Whatasapp Messaging Platform

1. I need a website to auto bulk sending whatsapp message. Bidder needs to tell me how many whatsapp msg can be sent every day 2. Allow me to upload contact list via csv or excel 3. Must compare new uploaded phone number and compare new ones with old ones, then delete duplicate phone number 4. the website can automatically generate along list of telephone number with a starting number 5. Scheduling to send out whatsapp. Scheduling is imporant as sending too many will bring in too much inquries which will overload the staff 6. can separate and detect the phont number into contact list to sms or whatsapp (if have whatsapp use whatsapp) If do not have whatsapp, do not send sms. Everytime must detect if a phone number has whatsapp, if yes, send whatsapp again. 7. report interface shows how many phone numbers have whatsapp, how many whatsapp are successfully sent, how many are not sucessfully sent, 8. the website can send text and image msg to whatsapp. Also, the webiste can receive text and image msg from whatsapp too. Bidder must be able to prove previous experience of doing similar project. Otherwise, don't bid. Thanks. Will not deposit any money till you can prove you have really been able to done the project. Will not deposit any money till I can test the website and find it basically functional.
