Depending on volume, a simple GSM data terminal and SIM card on the same
contract might suit your needs. Linux has good SMS sending capabilities
via the command line (getsms/putsms) I use this in a variety of ways
for my own uses (primarily to get notification of my remote servers health
or not via Nagios) It's a serial connection between the PC and terminal,
and you can send 2-3 a minute, if required.
A cheap terminal these days is:

(first one on the page)
I'm using one of these for both the phone and TXT facilities it offers -
it does the same job as the more expensive Siemens M35 brick I bought
a few years back and has a standard phone port (And as you have asterisk,
if you have a spare FXO port, you can connect it to the device then make
calls on the same contract to/from the mobile users and the main office -
might work out cheaper than going out via the PSTN or your VoIP carrier -
which is exactly what I'm using it for, so I get a double bonus)
So your on-going costs will be the cost of sending a TXT via the contract
on the SIM card you have. Orange used to have a good contract where for £20
a month you could send up to 2000 TXTs (IIRC).
FWIW: I was looking for bulkish services for a proejct some 2-3 years ago
that never got off the ground) and the main operators weren't interested
in dealing direct with me as I was only looking at 3-5000 TXTs a month. I
got the impression of "Go away sonny and come back when it's 3-5 million
a month..."
So a "carrier" I looked at a few years back was:
http://www.smscarrier.com/
You use a simple API to send TXTs to them via the Interweb. Charging
was cheap IIRC - in the order of 3p per message I think. (it's probably
changed though)
Good luck!
