[geeks] What do you get paid for wearing a pager?

[Patrick Giagnocavo]

Hi,

I have a client that wants to pay me a retainer fee for wearing a pager 
from 7AM to 7PM, Monday thru Friday.

Then they want to pay an hourly rate for any work I do for them (usual 
sysadmin stuff, plus of course fixing whatever the problem was that 
they actually page me for).

Kicker:  I need to respond within 15 minutes of a page.

I have done lots of sysadmin work, but really do not quite understand 
how to price the "wear pager and respond in 15 minutes" work.

What are *your* experiences or ideas?
