About how much can we expect to pay for a retainer fee for a lawyer who handles somewhat complex family law cases involving an ex and a minor child?

I am wanting to take my ex back to court now that I'm out of the military and in a place to do this financially. I haven't seen my daughter in 11 years but have faithfully paid my child support, had her on my medical and dental insurance, paid any other bills that arose that I was ordered to pay, etc. I let my ex move to IA (with our daughter) when my exes mom was sick with the express understanding that she would still make time for me to see my daughter, and right after that she just stopped letting me see her, completely ignoring the divorce decree. She has never followed the decree while I have every step of the way. I even took the parenting classes that she wanted me to take. She keeps calling for more money but won't get the child support switched over to IA because where it is now (in NE) I have to pay child support until she's 19 (in IA it's 18). She also told me recently (when she had an issue with another ex) she doesn't like the judge in IA because he favors equal rights,
