Trade Chat Selling Addon?

[Mortarius]

I'm not sure if this is even possible for addons, but is there such an addon that would allow me to create a sentence and then have it auto say it in Trade chat like every minute or two? For example:

WTS [Item Link] (Price), Please whisper!

And it would send this to Trade Chat on a timer every couple of minutes.

Thank you!

*Edit* Also wanted to just add to this so I didn't have to make multiple posts. Is it possible to have the Preview Window from MogIt placed in a static position instead of on the tooltip? I use Auctioneer and it overlaps that tooltip. =[
