Website functionality testing

I am looking for someone to help me to do some testing of some functionality for a website we have been working on. It is a membership database and i need someone to test how it works in terms of member registration and renewals/overdue payments, as well as testing how it works for setting up events and then for members to sign up for these events, and how the emails that are generated work for both sides work.

There are quite a number of different levels of membership and it is a bit confusing, and I need someone with an analytical mindset and logical brain to go through the process stage by stage and then to mark up how it works and any issues they find in such a way that they are easily understood by the web developer.

We will probably start on this early next week, so I would like to try and appoint someone to do the testing this week if possible.

I want someone to do this who knows their way reasonably well around the back end of a WordPress website.

If you have done this sort of thing before, that would be useful.

I have already done some initial testing of the registration process, but I don't really want to do anymore....

No idea how long we will need, but maybe about 3 days work in total, though perhaps not all at the same time.

Ideally looking for a native English speaker.
