Anonymous Job Openings in Boise

I came across a couple of anonymous job openings posted on the Boise Craigslist site this morning:

Marketing Concept/Copywriter - Looking for a copywriting concept pro.
Art Director/Graphic Designer - Looking for an experienced designer who can create just about anything.

Anyone care to shed some light on who might be doing the hiring?

UPDATE: I received a tip that these are positions at Rizen Creative in Boise.
