Clouds ???

I am in dire need of a 'cloud' emitter and have failed miserably to produce anything remotely like a cloud. Does anyone know where I can buy one or anyone here want to write one? (i'll pay of course).
What I'm looking for is to produce flattened cumulus style clouds to be placed about 30m above the surface so that a skybuild can seem to rest on top. I need to cover an area about 40 to 50 m square, multiple emitters are not a problem.

This belongs in products wanted forum, but since I'm nice, I'll suggest you search inworld for 'The Particle Laboratory' many free and example scripts with a wide range of effects and very easy to tweak to your liking

The perfect (and free!) suggestion Void. As a matter of fact, I went there recently (did way back when I was a newb, but I didn't really know scripting either). I wound up spending 2 hours going from kiosk to kiosk, looking at the information and example displays there. It's been redone recently, and it's VERY well laid out. Each koisk presents clear, concise, easy to understand explanations of each particle function. Some displays just have an info kiosk that presents info as hovertext, others include a notecard with an example script, and short explanation, and all displays have a visual example of the topic being discussed. In the middle is a small sandbox for experimentation along with a wall of free sample scripts contained in notecards. I'm sure the smoke example could be easily modified to create a cloud effect. Hat's off to JP for his awesome in-world walkthrough of one of LSL's most difficult functions (28 parameters!) to master.
