Office space for rent in Santiago?

Where can I get information on renting office space in Santiago? We're looking for something small that's in a centric area in Santiago (i.e. near a shopping center).

I've been searching through the web, but it's very difficult to find anything. We initially wanted to rent a virtual office, but apparently there's only one, and it's in Santo Domingo.

What's the current rate/month per square foot for office space?

Any help is appreciated.
Thanks.

Thanks for the post.
Where is Jardines close to? Would you happen to know approx how much rent would be for a small place?

Thanks again.

Thanks again for all the info!! All this interest in my question is just overwhelming!!!

Thanks again for all the posts!!!!!
