Build Stocks Trading Competition Website in Django

I need to build a Stock Trading simulation website that host trading competitions for users. Need register and login page, a stock search page, buy/sell functions, a portfolio visualization page and a ranking page. I need the site to be hosted on heroku with all database set up ready to go. The site need to look fresh and easy to use, with good html design on the front end as well. I have a good amount of coding in Django done, and is uploading the project folder here. I need you to finish and refine the functions, and do the html design work as well.
