Setting up 2 special groups....can you help me please?

Hello!
I've tried to create them since days, but i still can't find the good solution, so i thought i'll ask you, im sure you will solve it.
1. I would like to create a group, it's called trial.
trial groups should support:
- Auto join to the group after the registration (i can do this now)
- The group member can access EVERYTHING (payment section/downloads too) on my site for TRIAL period (for example it would be 2 days)
- After the trial period is over, he should get a message about it via mail or pm, about he can't use anymore this group and can't join again, if he wants to access everything on the site again, he should join the payment group.
Is it possible somehow? How? can someone write it down step by step, please, it would be very helpful for me !
2. Payment Group should be support the following:
- He can join the group, but admin can approve him.
- In this group as member he can access everything on the site ( ican do this)
- Before his payment period is over he should get a warning pm or mail automatically about it
OR
- When his payment period is over disable every access from the site and he should get a message about it
Is it possible somehow?
Or any similar idea would be great for me, i've just written down how i imagine this all.
I know that admin includes Group admin section, but the truth is that im lost in these options yet <img>
Thanks in advance!
