Intuitive Package Setting Plugin

For those of us who find the membership system tricky to manage optimally:

Set up a Membership plugin which acts like a decision tree and menu driven. The sequence might go like this:

1 How much do you wish to charge for membership?
2 How long should membership last?
3 What are the features of membership [present selectable options]
4 Press to configure membership
5 Description of what features the membership comprises – which has just been configured

Configure listing Packages in the same way:

1 – What do you want to call this listing Package?
2 – How long should the listing last?
3 – What features should the listing comprise?
4 – How much should the listing cost?
5 – What do you want to do when the listing expires?
5 – Select a Package Template

Ensure this will take all the necessary precursors of all the linked functions – so the Packages are correctly configured.
