Integration of bot chat on Facebook (manychat) into a sales strategy with a weekly webinar

I am running a weekly sales webinar to sell a course. I want to integrate manychat in the strategy What do I want manychat to do? Two things. 1. Notify registered users through facebook msn that the webinar will comment. I want to boost attendance to the event live 2. Send commercial messages during the 2 days following the webinar But I need that the messages of sale and notices do not receive them old users of the webinar This type of flows in email marketing tools is how to make them But in manychat I feel very lost I know I want you to make the tool. I have in my mind the flow of communication But I need someone to take care of all the technical part of configuration Project Type: One-time project You will be asked to answer the following questions when submitting a proposal: Do you have experience in "evergreen" sales funnels? Strategies that are repeated every week Do you have any questions about the job description? Do you have suggestions to make this project run successfully? Did you set up a similar BOT before? If it were necessary to make some configuration between my webinar system, email marketing and manychat via zapier would you do it? PD: Excuse my limited English.
