hey guys, in a bit of a technical issue for pricing rn, I am building a bot for a content creator, their site gets 4-6k visits a day, how can I price the monthly maintenance cost for them? (How much would botpress charge for let's say 5k conversations). I am building the bot for free but am trying to only charge for maintenance so that I have a high chance of closing them as my first "client" for a case study to get referrals and use them on my agency website to get more clients.
