Make a pop-up window on the site for accepting applications

Good afternoon everyone
I need on a ready-made site - to complete the pop-up (to receive contacts) - a window where people can leave their contact to contact
This contact will be processed through a script and sent to the bot (create a bot and a script)
The bot in telegram accepts contacts - which I can view (conditionally a gasket for accepting applications) in the form of a bot

Layout of the site in html
Bekenda - none

I want to see applications, such as:
- Your contact telegrams for communication
- the cost of work and how much time is needed for development
- how do you see the solution (3 points conditionally)

I need to do it today.
