Need help setting up a chatbot surrounding

I am looking for someone to help me set up a chatbot on a Windows or Linux system, which I plan to use and train local LLMs on. The purpose of the chatbot is to provide customer service and generate leads. I am expecting the chatbot to handle less than 100 interactions per day. So, if you have experience setting up a chatbot on Windows or Linux, and you believe you can help me accomplish the goals I have listed, please get in touch. Thank you!
