Best Way To Create 1 page Sub-domain landing pages for your team that you control

Hi...wish everyone good luck with the 1.6 billion dollar mega lottery tonight

Objective:
> I wish to host & create 10 sub-domains with a VPS plan with my hosting company!
> I will issue and assign to each of my 10 sales team members 1 sub-domain each.
> Each team member will get 5 different free squeeze pages each offering a different free educational report to be used to generate leads and build their email list
> If i want to stop a team member from getting access to the free subdomain 1 page website I issued to them how do i do what settings will allow me stop access immediately at will
> On each sub-domain I create for each team member how would i setup that sub-domain to create 5 separate distinct pages that will display a distint URL for each of the 5 different Free Reports they will be offering so how can i accomlish this
example below:
This is the subdomain i create for team member #1 = www(dot)mary(dot)ABC(dot)com and i want Mary to use this sub-domain to offer any of the 5 free reports below so what essentially I i will have to do to setup the subdomain so that mary can share a separate distinct link for each of the 5 reports below. I will be using wordpress by the way, so when each of distinct URL LINKS are promoted online they will go to a different landing for each of the 5 reports
