Bulk Cell Phone Text Messaging?

I was wondering if anyone knew of such a service, basically im looking for something to add to a website that will 'collect' cell phone numbers where i can schedule daily or weekly pre-determined text messages to be sent to the numbers that were collected.

Im putting together a couple of concepts for a bar/nightclub website and rather than just simply having an email collection box for a web based newsletter i was curious to see if it would be possible to send out real-time text messages letting cell phone subscribers know what was happening on any given night at a bar/club.

If you simply made an email signup that said "give us your phone number and choose which carrier from this dropdown to get coupons and discounts on your cell phone", then you could email SMS messages directly to their cell phones using the same software as you send regular emails.

For example, Sprint' SMS email gateway is xxxxxxxxx@messaging.sprintpcs.com (xxxxxxxxxx being the phone number) and Verizon's is something like xxxxxxxxxx@vzwmsgs.com.

so you'd just have to append the correct @whatever.com to their cell number and you'd be done.

If you want them to actually sign up through their phone, I think you have to work that out through the cell carriers.
