What people charge
Day rates members published themselves. Nothing here is a recommendation.
Minimums
Your own rate is your minimum. Nobody can send you a booking request below the day rate you publish. If you want to take cheaper work, you lower your own number — nobody can talk you down through this product.
Rates come from what members entered on their own profiles. Add yours on your profile — it is what makes this useful to everyone, including you the next time someone lowballs you.
