How distribute report to external subscribes?

We need to invoke every evening report for all our customers, and send
to him by email and fax according customer profile.
I read about scheduling and ability to send email but in our situation
it seem more complicated.
I not sure how deal with:
+Invoke report for each subscribe according his profile
+even if i send for all customer the same report, how I make schedule
that invoke the same report for each customer by his ID?
+how make schedule that send to each subcribe by his mail address?
+How I can make schedule to send by Fax (this is can be resolve by
Emailing to some Mail to Fax system, So for now we can ignore this Q)

In short, i need to invoke report and save it programmatically?I find somthing:
