Need to add some function on myBB forum script and install on host

I need someone to change the myBB forum script. You need to add functions and change the color to red black Of the functions I need: - Chat - Rankovi - Sections, access to sections depends on the rank of the member. - Rank seller, and section for sellers and ads. - Places for ads. Banners ... - A page for the purchase of ranks. - Control the registration from the admin panel. Let's say the admin can manually accept the registration requirements. - Black List, section where there will be a list of ban members.   - Change in color in black and red An example of this site is [login to view URL] Please read everything first, and then just send your bid. Also write the right price and the right timeline
