How much for t-shirts designs

[Josu]

Recently a company as asked me to make some designs for their t-shirts, and then asked for my rates. but i have never done something like that so i have no idea how much to charge.
does anyone know how much is a decent price?

I say it depends on the job's intricacy, but calculate a personal hourly rate that you value yourself at, and determine how long you'd think the job will take.

Although I've only looked into doing something similar, have you finished with that job? What did you end up doing?
