Budget: 27000 UAH Deadline: 15 days

Hello, Denis!
I am in 2nd place on the platform and specialize in developing chatbots and automating business processes. I work with services such as n8n/Make.com.
I have repeatedly implemented AI-Voice agents/consultants for incoming and outgoing calls, so we can easily do it for you as well. I am attaching the case.

online payment;

promo code system;

referral program;

saving all data in the database;

basic admin panel for management.

What we will do and why us

Frontend: responsive layout, animations, loading speed optimization (Next.js).

Backend: API on Go, server-side validation, logic for promo codes, referrals, and payments, transaction accounting.

Database: PostgreSQL (recommended) + minimal admin section (users, payments, promo codes).

Hello, Denis!
I can build this system through Make: I will connect a voice AI platform (Vapi or Bland) to your number +49, set up the conversation script in German, create a Telegram bot that receives requests and gives you buttons for confirmation or changing the time, after your response a trigger will initiate a callback to the client. I will set up WhatsApp and Telegram chatbots through API with the same booking and confirmation logic through your Telegram.
Please let me know:
- Do you have a telephony provider for the number +49 or do you need to connect one (Twilio, Telnyx)?
- Is there already a calendar for appointments being used (Google Calendar, other) or should it be created from scratch?
- Is the conversation script for the assistant already ready or does it need to be developed?

I will be able to provide the exact cost and timeline after reviewing the detailed technical specifications.
Let's discuss!

The price and development time will depend on your knowledge base (more precisely, its implementation for AI).

The actual development of automation will take from 1 to 2 hours (provided that everything needed for it is available: bots, access, verifications, etc.).

Hello! The project is generally real and technically feasible. A chat-bot in Telegram and WhatsApp can be implemented relatively quickly — it will be able to accept appointment requests, operate in German, send information about inquiries in Telegram, and allow for confirming or suggesting an alternative appointment time. The estimated development time for the chat-bot is 3-4 weeks (including testing), and the cost is €500–1500.

A voice assistant for automatically answering calls to a mobile number is a significantly more complex solution. It requires integration with telephony, setting up dialogue scenarios, speech recognition and synthesis in German, as well as thorough testing. Developing such a solution usually takes 7-8 weeks, and the cost starts from €1,500, with possible monthly expenses for telephony and AI services.

Given the complexity of the voice agent, I would recommend starting with a simpler and more reliable solution — the chat-bot, testing the business logic and appointment scenarios, and only after that adding the voice assistant as the next stage of system development.
