Freelance Rig Job: Estate time? How much money?

Hi fellow tech artists!

I wonder, how long would you estate it to take to make a full main character rig for a freelance job? Realistic graphic, no AAA (kinda indie), third person. I guess I could do this in three days so I will probably ask for a week. Does this sound realistic or too much/little? And how much should I ask for?! This is my first freelance job ever! Have no idea… This is Europe, Sweden/Denmark to be exact, where the starting salary for me at a companies would be around € 2500/month before taxes.

Thanks!
