Auctions website for a Car company. Car Auctions Webiste. - open to bidding

I want to create a website for auctions. Its a car auctions website. It needs to be done using wordpress. I need a very good design. Functions includes : 1. Live streaming functionality of auctions. (i.e. we will either keep a mobile or camera at the place where auctions are happening. Users can come and witness the live auction video anywhere in the world and will be able to participate in bidding. 2. Other basic auctions functionality 3. Provision to make online payment via a payment gateway ( Payment Gateway details, I will provide ) 4. Site should be speed optimized not more than 4 seconds for loading 5. You can take a base wordpress theme and customize it. ( if you give a good price, i can think about paying for the theme purchase ) Looking for a long term relationship, i have many such projects in hand. I need to website to be delivered in 20 days after accepting the work. First I need the website layout design in jpeg> i will confirm and make necessary changes and then we can proceed with the development. I will create milestone payments for part amount only. Once you create the design, i will create for full amount. If you read and agree then bid. While bidding please mention the term " I agree to the terms" So i know you read my complete requirement.
