We need a Web app like whatsapp web console which will be use to communication between two type of users.
Male and Female users
Male will talk (message) with female users and pay per message fee to send message to female. 1st few message will be free ( 5 messages ) after that male will need to pay per message fee of female user to carry on messaging. Female user will able to send any amount of message she wants. Only male needs to pay
There will be option for female user to send invoice within active message window, for Male user to ask them to pay invoice which will active free mode of messaging.
E.g female user ask to $10 for free message. Male user pay $10 and male user wouldn’t have to pay per message fee of Female until Female user stop the free mode. After the free mode end , per message fee will be active for that male who paid free mode.
Look/feel and how it should work, Best example with some the core feature is this one
Message and all the other core features such as read, edit notifications etc. We will use twilio
https://www.twilio.com/ip-messaging/features ( it got us cover everything )
We will use this theme for our site
