Cell Phone Texting Integration

I would like to know if you can create some kind of Cell Phone Texting integration into my site. I am in the process of having a special search site created. It will be paid member based, so that when they are online they login and use the site. I want them to be able to register their cell phone number with my site so that they can text a search term to a number that would send the term to my website. Then after verifying the users cell phone number the site would ruin the search and then send the results back to the users cell phone in one of two forms. For standard cell phones they would get a basic text. For smart phones they would get an excel file. The user would set up which type of cell phone they have when they register. Can this be done? Does it require some additional subscriptions with outside providers? Please let me know along with a bid if possible. Thanks!
