Sociopath Community

Personalized and/or customizable decals for the bikes.

Insurance on the custom work done.

Detailed history of the customization in an expensive album form.

Whatever allows you to suck the money out of the sucker in general.

i'm not sure yet what you specifcally could put on it but here is a list of ideas of what it can be put on and in what way

i doubt people would want something saying "i'm a sociopath"

but if it was in the form of a joke it might be more attractive

temporary tattoos

mouse pads

mouse

keyboards

hats

iphone/andriod covers ect..

stickers for motor bikes or for bike helmets

other forms of stickers

joke gift cards

mugs/cups maybe someone might like a skull shaped cup

http://www.roadkilltshirts.com/  they could give ideas on how you can present a text design for a tshort or cup what ever

this is cheat engine store i had told them they should make a store and they eventually did

http://cheatengine.scratchdog.com/   this is also more ideas from someone who was in the similar boat once as you

Stuff from ebay mindless buyers will buy for more. profit!

you also could have GAMES for the website that allow you to buy like points to get power ups on the game this is another way to make money

i'm not talking restricting people in the game the game works even without points but anyone who wants to get ahead can take short cuts and pay you

make up and hair dyes also could work for histrionics

 art, sex, water....
