I'm considering a freelance offer for a startup in the US (I'm European) and I'd like to know if I should request some sort of down-payment for these initial hours.
Basically I don't want to get ripped-off and I'm thinking that if I don't have this mechanism, then the client can simply not pay me after I work for some time and there's nothing I can do about it.
I reckon the project will be done in roughly 80h or so and I want to bill weekly.
So, two questions actually:
1) Should I use down-payment for an hourly-based gig?
2) What would be a reasonable net-X? How many days?
