Find a local shop with a vinyl cutter and try working out a custom pattern with them for the vinyl.  I prefer to try to stay away from pre-made designs and think custom is always the way to go.  If you find a good shop near you that cuts the vinyl good chances that the person who works there is a graphic designer and will be excited to work on a custom graphic design for a blank canvas like that.  Just give him a few pictures of what you like and let him create something custom from there.  But i would start with vinyl instead of paint since paint is more expensive to remove and change.  If you really like a design then you can always go back and get it painted on.

Heck for the price you pay for a full sticker job it would be cheaper to pay someone to air brush.  Air brushing Pisses all over stickers and looks great.  You will not find 2 bikes with the same air brush style on it.

It worked out $180 cheaper for me to air brush then get fancy stickers made up for my GSXes550. 

Here is my $7 fixer: It's the Metal Mulishia logo! It is going to go away soon. I'm still trying to figure out what I want!
