Whatsapp bulk sending Website or Scripting

If you've develop this solution for some one, please quote a price. I'm looking for ready solution rather than developing it. Please message me your sample solution demo before accept. Thank you. 1. I need a website extension to auto bulk sending whatsapp message (From Different WhatsApp Account). 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 (e.g. 91234567, 91234568,91234569,9200000, 92000001, 9200002...and so on. 5. Scheduling to send out whatsapp. Scheduling is important as sending too many will bring in too much inquries which will overload the staff 6. can separate and detect the phone 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. besides text, can send and receive from image. Video is not necessary at this stage 9. 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. Skills Needed : MySQL, PHP, Android, iPhone, Web, Data Processing
