Wage Garnishment alternative

I have a wage garnishment notice, went to court, filled out an order to show cause that i just could not afford the amount they were going to take, rent, taking care of elderly mother, transportation costs to and from work as I have no car, other bills, food. Judge would not sign off on it. Can I still attempt to negotiate with collection agency for a lump sum? Thank you.....Sum is $1,800, of course so much of that is interest and legal fees.
