Fog is INCLUDED in your lighting budget!  Be aware though, that asthmatics sometimes have trouble with fog effects, so plan accordingly.  I actually use HAZE, which is different and lighter than fog, and causes much fewer problems, but still, be cautious.

Giveaways, such as CDs go for the market price. It's whatever it costs me to purchase, and the money for these items would need to be fronted during our initial consultation meeting.
