LeadPages type script

I want a script that works like sites like LeadPages dot com that allow users to create a profile, drag and drop commerce editor, their own control panel access and a ability to use the customers chosen name as like a sub domain to the original url name ie: [login to view URL] like in this example: [login to view URL] Would also like to have monthly subscriptions to allow customers to create these pages like a reaccuring payment with paypal, CashApp, etc. I don't want it to be free as these other sites allow. also, a full script control access Admin or cpanel like . I know of many open source scripts that come close to what i need but need a couple extra things to fit me. I want to be able to test the script you propose selling me. I must check that everything works. I've always been an excellent upfront buyer.
