You distinguish "chargable" and "non-chargable" time. While, technically, this may be a necessity, you ultimately need to be billing for the entire time necessary to run the event and figuring that into the "chargable" time.

I'd question whether you need all of the stuff you are expecting. I imagine that most clowns in the U.S. "pack tight" and don't have to carry all kinds of stuff which requires a lengthy load in and out. (I fit my entire show into one or two suitcases - the necessity for the 2nd depending largely upon whether I need extra stuff for juggling or a "big impact" gag that requires more substantial props.) For example, if a speaker system really necessary if you have a party for a dozen kids and the few parents who attend in a backyard or basement? Now, given, if you can offer something greater or have big events and you find buyers, awesome! But now you're probably looking at being there a longer time and acting as the center of the party for maybe three entire hours. You'll likely do everything from DJ to balloons and all that's in between. And you'll charge darn good money for it, too.

It is ultimately a matter of understanding and finding your market then catering to it properly.
