Need conversational designer for a Facebook Chatbot shopping assistant

Looking for an experienced conversational designer to design a prototype for a Facebook chatbot shopping assistant and the project involves mainly the below: 1. Analyse the current conversation data (about 10 past conversation) and proposal changes (we have a very raw prototype that needs to be improved or even rewrote); 2. Draw/Write the conversational flow (ideally with Chatfuel, or you can propose any better tool for prototyping) 3. Interview and tested the initial conversational flow (we will provide interviewees for remote communication, about 20 beta users) 4. Complete the final conversational flow. You will work with a team of mixed skill sets experts for this project (web-developers, data scientists, marketing experts etc). We expect these tasks could be done in 10 working days, but we could give a 3 weeks spans to complete. After you complete this project, if you prove to be good, we would hire you for another similar length for another round of conversational design iteration and improvement after the MVP is properly launched and have more testing data. Thanks for your time and please link your portfolios when apply.
