Hmmm...

After some thought, I'd say:

$100 - buy content and make galleries and free sites. (I'm with Patti)

$1000 - Either buy a couple of frontend designs, or take a design class at the local art/design school so I can do them myself.

$10000 - Buy new video and photograpghy equipment and open a production studio. After the equipment, I should have enough to get a couple decent models in.

$100000 - I'd invest it in real estate. I could think of a thousand ideas for online use but moving some of the bigger money offline goes hand and hand with my diversify ideology.
