Make a functional clone of a website with new design, colours, etc.

This is not a standard CMS website so if your skills are limited to WordPress, Drupal etc. you should not bid unless you are certain that you can do it. It would be best if you have an understanding of online gaming (Fortnite, Call of Duty, etc.) as a player, not as a programmer. I want to have a website built which offers all the same services and functionality as currently offered by [login to view URL] but I do not want any hacking or reverse-engineering done on that site. It is pretty basic functionality for facilitating online gamers to have a private wager on their online games. They deposit funds, one player sets up a challenge, when it is accepted both parties have the wager deducted from their account and the winner receives 90% of the total when the result has been verified. Players also are given a bonus account and the bonuses they receive are released 'on the drip' as they play more games. There is also a chat room. If you watch the video on the home page you will get an overview ([login to view URL]). IMPORTANT: Please investigate the site properly and make sure you understand everything that will be required before bidding.
