I would give some thought to how to make the working from home thing a positive to your customers... it provides you a lower base cost that you can pass to them... your "stuff" is always available in case they need late night / weekend support... etc...

Also, be wary of how you use the temp office spaces. I don't dislike them... just don't try to make it seem like it's your regular office. Being up front with them and explaining it's a meeting location only will help convey your desire to be professional and honest.
