Custom AI Chat Bot Development

I need an experienced developer to create a custom AI Chat Bot for my website. The bot should have the following functionalities: - Answer frequently asked questions posed by potential customers. - Schedule appointments, allowing customers to request specific time slots, choose from available time slots or have the bot automatically suggest available time slots based on customer order. - Send invoices to customers once appointments have been confirmed via chat and paid for. I need to create a custom AI Agent that will respond to customers that want to purchase services. This agent will need to respond to questions, provide pricing based on customer responses, schedule appointments depending on availability using Google Calendar, and send invoices for payments by creating an invoice through Stripe. This AI Agent will need to generate a custom Stripe invoice. Backend API’s for Stripe and Google Calendar will be necessary unless there are libraries/3rd party integrations with code that can do this. If this is done successfully, you will have the opportunity to work on a customer Management Bot. Ideal candidates for this job should demonstrate a strong understanding of AI technology and should have previous experience developing similar bots. Knowledge on website integration will be essential as well. I look forward to receiving your proposals. Sample Conversation: Customer: Hi, how much would it cost to purchase 2 tutorings and 1 resume review? AI Chat Bot: Welcome! Happy to assist. Pricing for 2 tutoring services and 1 resume review will be $150 USD. Where are you located (type zip code or address)? Customer: Great! I am located in New Jersey 11554. AI Chat Bot: Perfect. You are within service range. Are you available Wednesday between 10am - 3pm date or Friday 9am - 6pm? Customer: Yes, those dates work. Let’s do Wednesday. AI Chat Bot: Please be ready Wednesday. Your appointment will be scheduled for 10 am sharp. Let’s proceed with the invoice: (web link generated from stripe for secure checkout) Must pay in full to confirm booking. Once booked, you will receive an email and confirmation via phone from customer service to confirm everything is set. Contract and client profile will be setup manually over phone with a dedicated account manager. Customer: *Pays via Stripe link. Developer Instructions: Feel free to use any AI model of choice, Chat GPT is okay. IF there are better/more dedicated models for customer management / sales please use. Looking to create a model that will be on the backend for online chat dialogue. Bot must be trained and work properly. I can help assist since I am a technical programmer but not well versed in ai agents. This bot must make invoices, which means it needs to calculate prices. I will need to feed this AI model prices and time allocation along with pricing structure. For Example: If customer wants 3 tutoring sessions it will need to find and block off 3 hours of available time. If customer wanted 1, the bot will have to recommend time slots that we have available for 1 hour. Model will spit out available times to confirm with customer. Once time has been blocked on the calendar invoice has to be sent for $ amount. (Stripe API seems promising for this… but feel free to use any solution) For example: If customer wants 3 hours of tutoring, the bot will have to generate a stripe payment link for $300 ($100/hr). Bot must not book time on calendar unless that time slot has been paid for… not sure how this can work but not biggest issue to start. This is very straightforward algorithm we have to create. I want it fully customized which is why I am looking for someone technical and proficient with AI and code. Please send proposals $ and time frame. Thank you. Look forward to connecting. Questions: How will/could enhancements be made? Let’s say if I wanted to train the AI Agent to accept a discount code? Or generate a contract post booking and payment confirmation? How long would this kind of update take to train the AI agent/ update the model? Looking for the most efficient model to quickly implement future updates.
