Sounds like you need some kind of diary program.  When someone pays
their dues, you record how much and when, and then set two future events
to happen.  An expiry date that disables their website, and an invoice
date for at least a couple of weeks before the expiry.

If you really are only a small group, you mightn't even need to automate
it, just use an ordinary non-computer desk diary.  But there are various
calendar programs about, and you can set what happens on those dates,
including running programs rather than just popping up messages or
playing alarm noises.  I dare say you could find one that would let you
run a script on a date that could do the emailing and account disabling.

i.e. Have a look at what "diary" or "calendar" programs you can easily
install, and see if any fit your needs.

All mail to my mailbox is automatically deleted, there is no point
trying to privately email me, I will only read messages posted to the
public lists.

George Orwell's '1984' was supposed to be a warning against tyranny, not
a set of instructions for supposedly democratic governments.
