hotspot, pppoe and Hotspot+pppoe

Dear Sirs
I have some questions, I hope we can share to find good solutions
before i start my my questions i will explain what I have and what i am going to do.
1- I have installed hotspot server
2- I have installed PPPOE server
3- hotspot and PPPOE with different range
4- all users created via usermanager
5- all users working in quota.
6- main internet comes from ISP via pppoe client.
7- my total traffic is 10 Mbps leased line.

now my questions is :
1- I would like to create new users group working monthly.
2- the users just sharing with 2 Mbps from 10 Mbps ( that is mean 8 Mbps for the users who are working in quote and 2 Mbps for the users who are working monthly).
3- I would like to make profile 1 Mbps and add 20 users to apply 1:10 sharing.
4- but I would like also to allow that users to use hotspot if they are away but they have to be share in same 2 Mbps

I have some ideas in my mind but number 4 i couldn’t find any solutions to pass the problem.

please help me
thanks

Note: there are possibility to divide my traffic from ISP to 2 accounts first is 8 Mbps and other 2 Mbps.

So sorry I think i write it in wrong place, dear admin please delete the this topic because i will do it in the general
thank you
