Full custody of Natalia

Words can't describe how broken my heart is for my 10 year old daughter. Natalias mother continues to make bad and negative unilateral decisions to take natalia away from me and hide her in the cult that she is a leader of. Lorena, natalias mother and my ex wife, married Bill Matthews, my father and leader of Solid Rock Church in Elk River, MN. Since then there goal and mission has been to steal Natalia from having any type of good and normal life and certainly keep her from any contact with me, her real father. I have 50% legal and physical custody but Lorena has decided I can no longer see or talk to Natalia and for quite literally no logical or actual reason. Natalia needs to be given a good normal and healthy life, which I can provide for her. I will be going back to court for full physical and legal custody. It will cost from $5,000 upward. I am just trying to raise a little bit to help toward the cost.
