Budget: $10 – $30 USD

(Bid for suggestion)
I am in need of a talented developer to help me with suggestions for the route to take for the addition of an AI assistant chatbot with an avatar for my website. The chatbot will serve multiple functions including providing weather updates, managing my schedule, acting as an alarm clock, and displaying news RSS feeds.
i will add skills to read from wordpress usermeta, custom post types, etc

i need to know the best route for anticipated 100k users using this assistant, should i use openai playground/chatgpt40 , claude sonnet 3.5, or add llama to my gpu server, i want to use whisper tech for communication since its free

im looking to pay someone for the proper suggestion, might even hire to setup if affordable
