Instragram Sales Chatbot for Handmaid ceramics

I am trying to develop an Instagram chatbot (direct messages) for my business Handmaid Ceramics. I have 7k followers on argentina. The chatbot should be in spanish and act as a salesperson. It needs to reach out automátically to a specific number of followers (randomly selected). If lead doesn't respond the chatbot should send 4 messages before stoping. I should be able to edit this messages before masivley sending them. It should be able to send payment links, and have conversion as its main goal. I want it to be based on GPT so it can simulate a real life salesperson. I also want to have the capacity to iterate on the prompt and to add new example conversations. Additionally, i would like to add context such as an updated pricelist and FAQs.
