I'd keep the 7d.
While the swivel screen and difference in price make the 60d appear more attractive NOW (you know, the "always greener..." sort of thing), you'll likely soon realize the advantages of the 7d (like the screen that doesn't black out when you press record) outweigh the negatives.
Besides, one more thing the 7d has going for it is its better build. You say you're plan to produce advertising videos. One of the most important factors in choosing equipment to do commercial work, is reliability. It is both personally embarrassing and costly in terms of business when an item breaks down, even if it is only for small-town clients (maybe more so, since you may have to live in the same community as them). The near-certainty that a piece of gear will keep working in difficult situations is what labels certain cameras as professional, and, in turn, gives the photographer greater confidence in appearing as a pro.
Coming from someone who doesn't really trust anything below the level of the 1D series, perhaps my advice should be taken with a grain of salt. And, as I shoot on the ocean about 100 days a year, my cameras have been know to acquire a few of them!
