Build a facebook bot for messenger, named brobot and a landing page for the service

Hello, i need to make a bot, also with heroku for messanger. This bot will have to do these actions: me: Hello brobot, I want to go to the movies tonight at 20. Could you ask to my friends who would go? brobot: Hello user, for which city do you want me to search me: Milan brobot: ok i'll do it asap :) me: thanks brobot brobot: u're welcome my friend, there are 5 friends in milan and 2 accepted, where is the cinema? me: Great, it's in xyz street brobot: great, i'll tell them to be today at 20 in xyz street. Do you want me also to save the time in to your calendar me: ok brobot, save it (integration with google calendar, approved) brobot: perfect, the date is saved, your friends will receive an alarm 30 minutes before, do you want me to organize a group between all of u? me: yes perfect brobot! thank you brobot: u're welcome bro! :) This would be the kind of bot i'd need. This is just phase 1 of brobot. I'd need also a landing page with sign up and accept brobot. I can accept also, and i am willing to give equity for the project with co. in ireland for whom it might be interested. I wait for your proposals, bye
