I need a website similar to [url removed, login to view] but where registered users in our system, can send massive messages to different contacts even if they are registered as their contacts. These numbers and messages will be uploaded using an xls or xlsx file, you will also have the possibility to send videos, images, geolocation, file of any type or contact (vcard).
No advance or partial payment will be made. The payment will be made "EXCLUSIVELY" when the project is finished and tested.
I need you to make an offer if you really have the ability to develop this project.
They must also give technical support for 6 months
