Help with Ancillary probate in Blaine County Ok

Hello, My Father passed last November in Georgia, and left me a small mineral rights claim in Blaine County, OK. I have determined that this needs to go through Ancillary probate in that county. Is this something that can be done by an individual or is it necessary to hire an attorney. If an attorney is required does anyone know of one that they could recommend? I have contacted one but have heard nothing back from them for a month or so. Thank you for any help with this
