I want to have my children 50- 50 and am willing to move where they reside in the next county over. we had a court order put in place 7months ago

If you don't have 50-50 custody now, you'd need to show a court why things have changed, since the last court order was issued, in a way that makes this the right thing to do now, and that the change of custody is in the children's best interests.  This probably isn't the sort of case that you can present effectively, without a lawyer, because the decisions are usually very sensitive to the detailed facts of the particular people involved.

Responsibility for healthcare usually depends on the money and insurance available to the parents.
