Marketing Idea:Mass Text Blast?

[Leah Bonner]

I know sms marketing is becoming bigger and bigger lately so I recently found a site that provides all cell phone numbers in 1 area code for $250... Now that's JUST the numbers since it is illegal to give any more info without someone to subscribe to something. 

Is it a smart choice to buy that list and mass blast a text / voicemail drop asking if they are looking to sell (or offer a referal fee for anyone looking to sell... Or since thats a bit too sales-y I'd have to think of other opening statements that grabs attention) 
Not too focused on the wording I would use at this moment but is it a smart choice to blast that?

be brutally honest!
