I'm looking for someone to develop an app using twilio where a person can go to a particular webpage and type in phone number to text. Then every 10th or 15th or whatever number I decide can win a prize.
So if the 10th person wins then the text should say they won, etc.
If they didn't win, it needs to say something different that I decide on.
It needs to do this automatically.
Plus, I'll need to make this where I can change the code for a different phone number.
This should all work with Twilio.
Can you do this and what would be the cost?
