I was asked to design a website for a client. Personally, I'd work for free since I'm just in it for the experience of working with a client but they insist on paying me so I will get an idea as to how freelancing works and for them to know how much they should pay for future services. I have very little experience when it comes to real work since I'm still a student but I've had internships as a web designer/developer in some software companies here in my area.
I forgot to mention that I am located in the Philippines. Since it's a 3rd world country, I'm pretty sure the rates here are lower than most areas.
