I'm looking to build a chatbot for leads coming from my Facebook Marketplace ads. Here’s what I need the bot to do: 1-The user is trying to sell their phone and wants a price. 2-The bot should ask a series of structured questions (no free-text answers, only multiple-choice options) to collect the device details—exactly like the form on the external site. 3-After collecting this info, the bot should automatically send the data to an external website to get a price estimate. 4-The bot should take the website’s estimate and add 15% on top. The bot should show this adjusted offer to the user. 5-If the user accepts, the bot will share contact details for one of our local agents so they can coordinate a safe meet-up for inspection and payment. Reference website for the questions and flow: https://www.ecoatm.com/pages/sell I do not have any API, so you need to built it. Platform I'm currently using: ManyChat but I am open to any platform that you can suggest. Let me know if you can build this and send me your offer. Thank you
