I don't know if I should call it "sales job" or "business partnership".
I have a web service (US-based online advertisement).
It's very useful and in very high demand, so you probably won't have any difficulties selling it.
You have to be physically located in (or close to) some big US city, and meet new clients in person, collect payments from your old clients every now and then etc. You will also need to do some setup at your home so that other employees can remotely access your computer (this is needed for work).
There are several ways we can work together (regarding %, your responsibilities etc).
Best case scenario you should be able to just keep working with 5-10 clients you've found, and have enough for living.
Or more, if you'd like to take more responsibilities.
Anyways, shoot me an IM - we'll figure something out.
When you do send me a msg - please mention which city/state you're from.
