add chatbot and copilot to my sharepoint site

I am looking to add a chatbot and a copilot to my SharePoint site. I need the chatbot to have basic FAQs, as well as support for technical queries. No integration into any other tools or platforms is required, as I would just like it to exist on the SharePoint site. For the copilot, I am looking for it to provide support for technical queries, as well as support for file sharing and collaboration, task management, and calendar scheduling. Please let me know if you can help with this project and what your timeline and costs would be. Thank you!
