UI/UX Screens - Design/ Dev - Automotive Chatbot

I need someone with marketing, thinking and designing (UI/UX skills). For me, there will be 3 step selection process 1) I clarify PRD/requirements/needs 2) You prove you have thinking capability and design skills 3) I select/ award and we officially start.. I am waiting for step #2 unless you have question for #1 I need someone who can look at my solution/ offerings and focus on the best UI/UX experience for this chatbot for target audience. You design and develop HTML too. I have an AI/NLP based chatbot which is supposed to work like a virtual salesman. It will be trained with some data for a given car (it can respond for any car/VIN#) and through my own APIs, it will be able to get additional services/(Data/ negotiated car value and all). Overall impression will be - it is a virtual sales person whom you can ask questions or it can have readymade/flow so buyers/online visitors can get everything they need. If you ask me, I have implemented it in a way I don't like it so I will not be able to tell you how it should be. You need to design and suggest. I want you to think outside the box and suggest new UI/UX which appeals to my target audience (automotive sellers/buyers). My selection process is going to be simple: 1) I will show my demo site. You learn/understand my target audience or options. 2) You suggest one mock up or idea (either design or describe your approach/concept here) so I can select you. 3) You do full research and come up with design/code HTML for my chatbot. We may need 3 alternatives to choose from as part of project. If you are a person who needs clear requirements, wireframe and clear color choices and needs -- please do not bid.
