Multiple groups of roles in membership

Hi,
I am developing this website which requires multiple groups of roles inside membership.
Here is an example:
I want to create a group of states (would be the first group of roles):


* Oregon
* California
* Kansas
* Texas
* Ohio


And then a second group of profiles:


* Admin
* Section 1
* Section 2
* Section 3


Then I want to comine these groups, so for example:
* Patrick has Oregon and Section 1 role, so he can only access the state of Oregon and Section 1 module on the website.
* Laura has Kansas and Section 2 role, so she can only access the state of Kansas and Section 2 module on the website.
* John has Ohio, Texas and Admin and Section 1 roles, so he can only....


Do you understand what I mean? How can I achieve this with .net memberhip?
