So I read this but I have different circumstances:
I was contacted to do some freelance design for an ad agency. The project was supposed to be a rush job and finish within the week. It's three weeks later now and the client has basically asked for a totally new design after a million nitpicks from their client (their client is requesting the new design, not the agency).
I've already spent my limit of hours that I estimated for completion of this project (that was not discussed or written down). I foresee another 15+ hours at minimum considering how it's been going so far. Should I request more money? I signed their contract as a "vendor" so there wasn't any room for me to put in details regarding these things as I would have if it was my own contract. We agreed on a flat fee. Now I'll be working for less than minimum wage if this keeps up.
Plus, besides the money aspect, the time aspect is something I want to address. Three weeks (and counting!) for something that they told me was definitely due in one week. I don't want this to go on for months. What's the best way to bring this up? Do I have any way to ask for more money for the additional work?
