Call the court for a list of providers. Call your insurance company and ask for some names. Some drs do not do full evaluations and here you will wait a month or two to get into someone and sometimes it takes a few visits to do, then they have to write it all up.
Keep calling around and make an appointment, make sure you are clear on what you need for court and ask them if they are willing to do that.
Are you sure the courts did not give you a name of someone you have to go to?
