Additional work in 2nd phase for additional cost and time.
See below for well defined work needed for first phase
Develop simplified whatsapp like application
No need for phone calls or images or videos or video calls. Just need plain text based chat.
But need additional functionality -- calling, texting and emails using the phone native support rather than building into the app (to save time to develop the app).
No need for diseappearing self destructing images/chats
No web app
But otherwise should look and work like whatsapp
Skills you need

3. Send SMS, e-mail, make phone call using the UI from iPhone or Android respectively
4. Develop mobile UI backed by backend in cloud

The app must work on our iPhone, my android, using our API subscriptions and our cloud subscription.
To prove that you have read the ad, you must start your response with "PLEASE SEND ME YOUR DECK" in the first line. But we do not have a deck to share as you are developing a whatsapp like application. You should give me estimates for cost and timelines both.
