There is only one level here, that of a client.  You do not have to make any payments here as your retainer to Mr. Lagman has satisfied your obligations to enter this portal. You will need the passcode that Mr. Lagman gave you to satisfy the payment terms of client membership. (So don’t worry about entering any credit card information. Instead after you have entered your name and details skip to the last line and enter the passcode. Your access will then begin.)
