Develop Chatbot for sending image to remote server and get response

I’m looking for smart developer for long partnership. At first step need to make Chatbot for sending image to remote server and get response (using existing Chatbot framework/platform for Facebook Messenger, Line, Viber, etc.) I developed Beta-Version with manual code. Backend is: Python3, PostgreSQL, Json API. I would like to get up and running ASAP as such I am looking to leverage an existing opensource chatbot framework or online-constructor such as [login to view URL] (but I am open to other suggestions) which will have the logic, functionality and admin features out of the box. Chatbot functionality: Upon receipt of the image, our chatbot send it to remote server and get text response (via API JSON) with a series of predefined questions -- each of which will have a defined response (such as "Yes" or "No"), responses to the predefined list of questions may trigger the chatbot to take further actions. Check chatbot functions what I need online in: - facebook messenger [login to view URL] - webiste [login to view URL] (start facebook messenger chat widget to activate chat-bot) Also I plan to make this bot in different languages. The value of your proposal will be greater if you can help me translate the bot dialogs into languages other than English. I can provide by response: - chat-bot logic schema - API commands for sending image and get responce - my help & consultations in development To be considered, please include: 1. Your relevant experience developing, deploying and/or managing similar chatbot projects, 2. What Chatbot frameworks (if any) have you successfully worked with in the past? 3. What you will need to get started (server, predefined questions, etc.); and 4. Your fixed price bid for the project. Good luck bidding!
